+## Contributing to Mongoose
+
+### STOP!
+
+If you have a question about Mongoose (not a bug report) please post it to either [StackOverflow](http://stackoverflow.com/questions/tagged/mongoose), our [Google Group](http://groups.google.com/group/mongoose-orm), or on the #mongoosejs irc channel on freenode.
+
+### Reporting bugs
+
+- Before opening a new issue, look for existing [issues](https://github.com/learnboost/mongoose/issues) to avoid duplication. If the issue does not yet exist, [create one](https://github.com/learnboost/mongoose/issues/new).
+  - Please describe the issue you are experiencing, along with any associated stack trace.
+  - Please post code that reproduces the issue, the version of mongoose, node version, and mongodb version.
+  - _The source of this project is written in javascript, not coffeescript, therefore your bug reports should be written in javascript_. 
+  - In general, adding a "+1" comment to an existing issue does little to help get it resolved. A better way is to submit a well documented pull request with clean code and passing tests.
+
+### Requesting new features

+- Before opening a new issue, look for existing [issues](https://github.com/learnboost/mongoose/issues) to avoid duplication. If the issue does not yet exist, [create one](https://github.com/learnboost/mongoose/issues/new).
+- Please describe a use case for it
+- it would be ideal to include test cases as well
+- In general, adding a "+1" comment to an existing issue does little to help get it resolved. A better way is to submit a well documented pull request with clean code and passing tests.
+
+### Fixing bugs / Adding features
+
+- Before starting to write code, look for existing [issues](https://github.com/learnboost/mongoose/issues). That way you avoid working on something that might not be of interest or that has been addressed already in a different branch. You can create a new issue [here](https://github.com/learnboost/mongoose/issues/new).
+  - _The source of this project is written in javascript, not coffeescript, therefore your bug reports should be written in javascript_. 
+- Fork the [repo](https://github.com/learnboost/mongoose) _or_ for small documentation changes, navigate to the source on github and click the [Edit](https://github.com/blog/844-forking-with-the-edit-button) button.
+- Follow the general coding style of the rest of the project:
+  - 2 space tabs
+  - no trailing whitespace
+  - comma first
+  - inline documentation for new methods, class members, etc
+  - 1 space between conditionals/functions, and their parenthesis and curly braces
+    - `if (..) {`
+    - `for (..) {`
+    - `while (..) {`
+    - `function (err) {`
+- Write tests and make sure they pass (tests are in the [test](https://github.com/LearnBoost/mongoose/tree/master/test) directory).
+
+### Running the tests
+- Open a terminal and navigate to the root of the project
+- execute `npm install` to install the necessary dependencies
+- execute `make test` to run the tests (we're using [mocha](http://visionmedia.github.com/mocha/))
+  - or to execute a single test `T="-g 'some regexp that matches the test description'" make test`
+  - any mocha flags can be specified with T="..."
+
+### Documentation
+
+To contribute to the [API documentation](http://mongoosejs.com/docs/api.html) just make your changes to the inline documentation of the appropriate [source code](https://github.com/LearnBoost/mongoose/tree/master/lib) in the master branch and submit a [pull request](https://help.github.com/articles/using-pull-requests/). You might also use the github [Edit](https://github.com/blog/844-forking-with-the-edit-button) button.
+
+To contribute to the [guide](http://mongoosejs.com/docs/guide.html) or [quick start](http://mongoosejs.com/docs/index.html) docs, make your changes to the appropriate `.jade` files in the [docs](https://github.com/LearnBoost/mongoose/tree/master/docs) directory of the master branch and submit a pull request. Again, the [Edit](https://github.com/blog/844-forking-with-the-edit-button) button might work for you here.
+
+If you'd like to preview your documentation changes, first commit your changes to your local master branch, then execute `make docs` from the project root, which switches to the gh-pages branch, merges from master, and builds all the static pages for you. Now execute `node server.js` from the project root which will launch a local webserver where you can browse the documentation site locally. If all looks good, submit a [pull request](https://help.github.com/articles/using-pull-requests/) to the master branch with your changes.
+
+### Plugins website
+
+The [plugins](http://plugins.mongoosejs.com/) site is also an [open source project](https://github.com/aheckmann/mongooseplugins) that you can get involved with. Feel free to fork and improve it as well!
+
+### Sharing your projects
+
+All are welcome to share their creations which use mongoose on our [tumbler](http://mongoosejs.tumblr.com/). Just fill out the [simple submission form](http://mongoosejs.tumblr.com/submit).

+
+## Overview
+
+### Connecting to MongoDB
+
+First, we need to define a connection. If your app uses only one database, you should use `mongose.connect`. If you need to create additional connections, use `mongoose.createConnection`.
+
+Both `connect` and `createConnection` take a `mongodb://` URI, or the parameters `host, database, port, options`.
+
+    var mongoose = require('mongoose');
+
+    mongoose.connect('mongodb://localhost/my_database');
+
+Once connected, the `open` event is fired on the `Connection` instance. If you're using `mongoose.connect`, the `Connection` is `mongoose.connection`. Otherwise, `mongoose.createConnection` return value is a `Connection`.
+
+**Important!** Mongoose buffers all the commands until it's connected to the database. This means that you don't have to wait until it connects to MongoDB in order to define models, run queries, etc.
+
+### Defining a Model
+
+Models are defined through the `Schema` interface. 
+
+    var Schema = mongoose.Schema
+      , ObjectId = Schema.ObjectId;
+
+    var BlogPost = new Schema({
+        author    : ObjectId
+      , title     : String
+      , body      : String
+      , date      : Date
+    });
+
+Aside from defining the structure of your documents and the types of data you're storing, a Schema handles the definition of:
+
+* [Validators](http://mongoosejs.com/docs/validation.html) (async and sync)
+* [Defaults](http://mongoosejs.com/docs/api.html#schematype_SchemaType-default)
+* [Getters](http://mongoosejs.com/docs/api.html#schematype_SchemaType-get)
+* [Setters](http://mongoosejs.com/docs/api.html#schematype_SchemaType-set)
+* [Indexes](http://mongoosejs.com/docs/guide.html#indexes)
+* [Middleware](http://mongoosejs.com/docs/middleware.html)
+* [Methods](http://mongoosejs.com/docs/guide.html#methods) definition
+* [Statics](http://mongoosejs.com/docs/guide.html#statics) definition
+* [Plugins](http://mongoosejs.com/docs/plugins.html)
+* [pseudo-JOINs](http://mongoosejs.com/docs/populate.html)
+
+The following example shows some of these features:
+
+    var Comment = new Schema({
+        name  :  { type: String, default: 'hahaha' }
+      , age   :  { type: Number, min: 18, index: true }
+      , bio   :  { type: String, match: /[a-z]/ }
+      , date  :  { type: Date, default: Date.now }
+      , buff  :  Buffer
+    });
+
+    // a setter
+    Comment.path('name').set(function (v) {
+      return capitalize(v);
+    });
+
+    // middleware
+    Comment.pre('save', function (next) {
+      notify(this.get('email'));
+      next();
+    });
+
+Take a look at the example in `examples/schema.js` for an end-to-end example of a typical setup.
+
+### Accessing a Model
+
+Once we define a model through `mongoose.model('ModelName', mySchema)`, we can access it through the same function
+
+    var myModel = mongoose.model('ModelName');
+
+Or just do it all at once
+
+    var MyModel = mongoose.model('ModelName', mySchema);
+
+We can then instantiate it, and save it:
+
+    var instance = new MyModel();
+    instance.my.key = 'hello';
+    instance.save(function (err) {
+      //
+    });
+
+Or we can find documents from the same collection
+
+    MyModel.find({}, function (err, docs) {
+      // docs.forEach
+    });
+
+You can also `findOne`, `findById`, `update`, etc. For more details check out [the docs](http://mongoosejs.com/docs/queries.html).
+
+**Important!** If you opened a separate connection using `mongoose.createConnection()` but attempt to access the model through `mongoose.model('ModelName')` it will not work as expected since it is not hooked up to an active db connection. In this case access your model through the connection you created:
+
+    var conn = mongoose.createConnection('your connection string');
+    var MyModel = conn.model('ModelName', schema);
+    var m = new MyModel;
+    m.save() // works
+
+    vs
+
+    var conn = mongoose.createConnection('your connection string');
+    var MyModel = mongoose.model('ModelName', schema);
+    var m = new MyModel;
+    m.save() // does not work b/c the default connection object was never connected
+
+### Embedded Documents
+
+In the first example snippet, we defined a key in the Schema that looks like:
+
+    comments: [Comments]
+
+Where `Comments` is a `Schema` we created. This means that creating embedded documents is as simple as:
+
+    // retrieve my model
+    var BlogPost = mongoose.model('BlogPost');
+
+    // create a blog post
+    var post = new BlogPost();
+
+    // create a comment
+    post.comments.push({ title: 'My comment' });
+
+    post.save(function (err) {
+      if (!err) console.log('Success!');
+    });
+
+The same goes for removing them:
+
+    BlogPost.findById(myId, function (err, post) {
+      if (!err) {
+        post.comments[0].remove();
+        post.save(function (err) {
+          // do something
+        });
+      }
+    });
+
+Embedded documents enjoy all the same features as your models. Defaults, validators, middleware. Whenever an error occurs, it's bubbled to the `save()` error callback, so error handling is a snap!
+
+Mongoose interacts with your embedded documents in arrays _atomically_, out of the box.
+
+### Middleware
+
+See the [docs](http://mongoosejs.com/docs/middleware.html) page.
+
+#### Intercepting and mutating method arguments
+
+You can intercept method arguments via middleware.
+
+For example, this would allow you to broadcast changes about your Documents every time someone `set`s a path in your Document to a new value:
+
+    schema.pre('set', function (next, path, val, typel) {
+      // `this` is the current Document
+      this.emit('set', path, val);
+
+      // Pass control to the next pre
+      next();
+    });
+
+Moreover, you can mutate the incoming `method` arguments so that subsequent middleware see different values for those arguments. To do so, just pass the new values to `next`:
+
+    .pre(method, function firstPre (next, methodArg1, methodArg2) {
+      // Mutate methodArg1
+      next("altered-" + methodArg1.toString(), methodArg2);
+    })
+
+    // pre declaration is chainable
+    .pre(method, function secondPre (next, methodArg1, methodArg2) {
+      console.log(methodArg1);
+      // => 'altered-originalValOfMethodArg1' 
+      
+      console.log(methodArg2);
+      // => 'originalValOfMethodArg2' 
+      
+      // Passing no arguments to `next` automatically passes along the current argument values
+      // i.e., the following `next()` is equivalent to `next(methodArg1, methodArg2)`
+      // and also equivalent to, with the example method arg 
+      // values, `next('altered-originalValOfMethodArg1', 'originalValOfMethodArg2')`
+      next();
+    })
+
+#### Schema gotcha
+
+`type`, when used in a schema has special meaning within Mongoose. If your schema requires using `type` as a nested property you must use object notation:
+
+    new Schema({
+        broken: { type: Boolean }
+      , asset : {
+            name: String
+          , type: String // uh oh, it broke. asset will be interpreted as String
+        }
+    });
+
+    new Schema({
+        works: { type: Boolean }
+      , asset : {
+            name: String
+          , type: { type: String } // works. asset is an object with a type property
+        }
+    });
+
+### Driver access
+
+The driver being used defaults to [node-mongodb-native](https://github.com/mongodb/node-mongodb-native) and is directly accessible through `YourModel.collection`. **Note**: using the driver directly bypasses all Mongoose power-tools like validation, getters, setters, hooks, etc.

+ * Setters allow you to transform the data before it gets to the raw mongodb document and is set as a value on an actual key.
+ *
+ * Suppose you are implementing user registration for a website. Users provide an email and password, which gets saved to mongodb. The email is a string that you will want to normalize to lower case, in order to avoid one email having more than one account -- e.g., otherwise, avenue@q.com can be registered for 2 accounts via avenue@q.com and AvEnUe@Q.CoM.
+ *
+ * You can set up email lower case normalization easily via a Mongoose setter.

+/**
+ * Adds validator(s) for this document path.
+ *
+ * Validators always receive the value to validate as their first argument and must return `Boolean`. Returning false is interpreted as validation failure.
+ *

+ *
+ *     function validator (val) {
+ *       return val == 'something';
+ *     }
+ *
+ *     new Schema({ name: { type: String, validate: validator }});

+ *         { validator: validator, msg: 'uh oh' }
+ *       , { validator: fn, msg: 'failed' }

+ *     // or utilizing SchemaType methods directly:
+ *
+ *     var schema = new Schema({ name: 'string' });
+ *     schema.path('name').validate(validator, 'validation failed');
+ *
+ * ####Asynchronous validation:
+ *
+ * Passing a validator function that receives two arguments tells mongoose that the validator is an asynchronous validator. The second argument is an callback function that must be passed either `true` or `false` when validation is complete.
+ *
+ *     schema.path('name').validate(function (value, respond) {

+ *         ...
+ *         respond(false); // validation failed
+ *       })
+*      }, 'my error type');
+*
+ * You might use asynchronous validators to retreive other documents from the database to validate against or to meet other I/O bound validation needs.
+ *
+ * Validation occurs `pre('save')` or whenever you manually execute [document#validate](#document_Document-validate).
+ *
+ * If validation fails during `pre('save')` and no callback was passed to receive the error, an `error` event will be emitted on your Models associated db [connection](#connection_Connection), passing the validation error object along.
+ *
+ *     var conn = mongoose.createConnection(..);
+ *     conn.on('error', handleError);
+ *
+ *     var Product = conn.model('Product', yourSchema);
+ *     var dvd = new Product(..);
+ *     dvd.save(); // emits error on the `conn` above
+ *
+ * If you desire handling these errors at the Model level, attach an `error` listener to your Model and the event will instead be emitted there.
+ *
+ *     // registering an error listener on the Model lets us handle errors more locally
+ *     Product.on('error', handleError);

+hooks
+============
+
+Add pre and post middleware hooks to your JavaScript methods.
+
+## Installation
+    npm install hooks
+
+## Motivation
+Suppose you have a JavaScript object with a `save` method.
+
+It would be nice to be able to declare code that runs before `save` and after `save`.
+For example, you might want to run validation code before every `save`,
+and you might want to dispatch a job to a background job queue after `save`.
+
+One might have an urge to hard code this all into `save`, but that turns out to
+couple all these pieces of functionality (validation, save, and job creation) more
+tightly than is necessary. For example, what if someone does not want to do background
+job creation after the logical save? 
+
+It is nicer to tack on functionality using what we call `pre` and `post` hooks. These
+are functions that you define and that you direct to execute before or after particular
+methods.
+
+## Example
+We can use `hooks` to add validation and background jobs in the following way:
+
+    var hooks = require('hooks')
+      , Document = require('./path/to/some/document/constructor');
+
+    // Add hooks' methods: `hook`, `pre`, and `post`    
+    for (var k in hooks) {
+      Document[k] = hooks[k];
+    }
+
+    // Define a new method that is able to invoke pre and post middleware
+    Document.hook('save', Document.prototype.save);
+
+    // Define a middleware function to be invoked before 'save'
+    Document.pre('save', function validate (next) {
+      // The `this` context inside of `pre` and `post` functions
+      // is the Document instance
+      if (this.isValid()) next();      // next() passes control to the next middleware
+                                       // or to the target method itself
+      else next(new Error("Invalid")); // next(error) invokes an error callback
+    });
+
+    // Define a middleware function to be invoked after 'save'
+    Document.post('save', function createJob () {
+      this.sendToBackgroundQueue();
+    });
+
+If you already have defined `Document.prototype` methods for which you want pres and posts,
+then you do not need to explicitly invoke `Document.hook(...)`. Invoking `Document.pre(methodName, fn)`
+or `Document.post(methodName, fn)` will automatically and lazily change `Document.prototype[methodName]`
+so that it plays well with `hooks`. An equivalent way to implement the previous example is:
+
+```javascript
+var hooks = require('hooks')
+  , Document = require('./path/to/some/document/constructor');
+
+// Add hooks' methods: `hook`, `pre`, and `post`    
+for (var k in hooks) {
+  Document[k] = hooks[k];
+}
+
+Document.prototype.save = function () {
+  // ...
+};
+
+// Define a middleware function to be invoked before 'save'
+Document.pre('save', function validate (next) {
+  // The `this` context inside of `pre` and `post` functions
+  // is the Document instance
+  if (this.isValid()) next();      // next() passes control to the next middleware
+                                   // or to the target method itself
+  else next(new Error("Invalid")); // next(error) invokes an error callback
+});
+
+// Define a middleware function to be invoked after 'save'
+Document.post('save', function createJob () {
+  this.sendToBackgroundQueue();
+});
+```
+
+## Pres and Posts as Middleware
+We structure pres and posts as middleware to give you maximum flexibility:
+
+1. You can define **multiple** pres (or posts) for a single method.
+2. These pres (or posts) are then executed as a chain of methods.
+3. Any functions in this middleware chain can choose to halt the chain's execution by `next`ing an Error from that middleware function. If this occurs, then none of the other middleware in the chain will execute, and the main method (e.g., `save`) will not execute. This is nice, for example, when we don't want a document to save if it is invalid.
+
+## Defining multiple pres (or posts)
+`pre` is chainable, so you can define multiple pres via:
+    Document.pre('save', function (next, halt) {
+      console.log("hello");
+    }).pre('save', function (next, halt) {
+      console.log("world");
+    });
+
+As soon as one pre finishes executing, the next one will be invoked, and so on.
+
+## Error Handling
+You can define a default error handler by passing a 2nd function as the 3rd argument to `hook`:
+    Document.hook('set', function (path, val) {
+      this[path] = val;
+    }, function (err) {
+      // Handler the error here
+      console.error(err);
+    });
+
+Then, we can pass errors to this handler from a pre or post middleware function:
+    Document.pre('set', function (next, path, val) {
+      next(new Error());
+    });
+
+If you do not set up a default handler, then `hooks` makes the default handler that just throws the `Error`.
+
+The default error handler can be over-rided on a per method invocation basis.
+
+If the main method that you are surrounding with pre and post middleware expects its last argument to be a function
+with callback signature `function (error, ...)`, then that callback becomes the error handler, over-riding the default
+error handler you may have set up.
+   
+```javascript
+Document.hook('save', function (callback) {
+  // Save logic goes here
+  ...
+});
+
+var doc = new Document();
+doc.save( function (err, saved) {
+  // We can pass err via `next` in any of our pre or post middleware functions
+  if (err) console.error(err);
+  
+  // Rest of callback logic follows ...
+});
+```
+
+## Mutating Arguments via Middleware
+`pre` and `post` middleware can also accept the intended arguments for the method
+they augment. This is useful if you want to mutate the arguments before passing
+them along to the next middleware and eventually pass a mutated arguments list to
+the main method itself.
+
+As a simple example, let's define a method `set` that just sets a key, value pair.
+If we want to namespace the key, we can do so by adding a `pre` middleware hook
+that runs before `set`, alters the arguments by namespacing the `key` argument, and passes them onto `set`:
+
+    Document.hook('set', function (key, val) {
+      this[key] = val;
+    });
+    Document.pre('set', function (next, key, val) {
+      next('namespace-' + key, val);
+    });
+    var doc = new Document();
+    doc.set('hello', 'world');
+    console.log(doc.hello); // undefined
+    console.log(doc['namespace-hello']); // 'world'
+
+As you can see above, we pass arguments via `next`.
+
+If you are not mutating the arguments, then you can pass zero arguments
+to `next`, and the next middleware function will still have access
+to the arguments.
+
+    Document.hook('set', function (key, val) {
+      this[key] = val;
+    });
+    Document.pre('set', function (next, key, val) {
+      // I have access to key and val here
+      next(); // We don't need to pass anything to next

+    Document.pre('set', function (next, key, val) {
+      // And I still have access to the original key and val here
+      next();
+    });
+
+Finally, you can add arguments that downstream middleware can also see:
+
+    // Note that in the definition of `set`, there is no 3rd argument, options
+    Document.hook('set', function (key, val) {
+      // But...
+      var options = arguments[2]; // ...I have access to an options argument
+                                  // because of pre function pre2 (defined below)
+      console.log(options); // '{debug: true}'
+      this[key] = val;
+    });
+    Document.pre('set', function pre1 (next, key, val) {
+      // I only have access to key and val arguments
+      console.log(arguments.length); // 3
+      next(key, val, {debug: true});
+    });
+    Document.pre('set', function pre2 (next, key, val, options) {
+      console.log(arguments.length); // 4
+      console.log(options); // '{ debug: true}'
+      next();
+    });
+    Document.pre('set', function pre3 (next, key, val, options) {
+      // I still have access to key, val, AND the options argument introduced via the preceding middleware
+      console.log(arguments.length); // 4
+      console.log(options); // '{ debug: true}'
+      next();
+    });
+    
+    var doc = new Document()
+    doc.set('hey', 'there');
+
+## Parallel `pre` middleware
+
+All middleware up to this point has been "serial" middleware -- i.e., middleware whose logic
+is executed as a serial chain.
+
+Some scenarios call for parallel middleware -- i.e., middleware that can wait for several
+asynchronous services at once to respond.
+
+For instance, you may only want to save a Document only after you have checked
+that the Document is valid according to two different remote services.
+
+We accomplish asynchronous middleware by adding a second kind of flow control callback
+(the only flow control callback so far has been `next`), called `done`.
+
+- `next` passes control to the next middleware in the chain
+- `done` keeps track of how many parallel middleware have invoked `done` and passes
+   control to the target method when ALL parallel middleware have invoked `done`. If
+   you pass an `Error` to `done`, then the error is handled, and the main method that is
+   wrapped by pres and posts will not get invoked.
+
+We declare pre middleware that is parallel by passing a 3rd boolean argument to our `pre`
+definition method.
+
+We illustrate via the parallel validation example mentioned above:
+
+    Document.hook('save', function targetFn (callback) {
+      // Save logic goes here
+      // ...
+      // This only gets run once the two `done`s are both invoked via preOne and preTwo.
+    });
+
+                         // true marks this as parallel middleware
+    Document.pre('save', true, function preOne (next, doneOne, callback) {
+      remoteServiceOne.validate(this.serialize(), function (err, isValid) {
+        // The code in here will probably be run after the `next` below this block
+        // and could possibly be run after the console.log("Hola") in `preTwo
+        if (err) return doneOne(err);
+        if (isValid) doneOne();
+      });
+      next(); // Pass control to the next middleware
+    });
+    
+    // We will suppose that we need 2 different remote services to validate our document
+    Document.pre('save', true, function preTwo (next, doneTwo, callback) {
+      remoteServiceTwo.validate(this.serialize(), function (err, isValid) {
+        if (err) return doneTwo(err);
+        if (isValid) doneTwo();
+      });
+      next();
+    });
+    
+    // While preOne and preTwo are parallel, preThree is a serial pre middleware
+    Document.pre('save', function preThree (next, callback) {
+      next();
+    });
+    
+    var doc = new Document();
+    doc.save( function (err, doc) {
+      // Do stuff with the saved doc here...
+    });
+
+In the above example, flow control may happen in the following way:
+
+(1) doc.save -> (2) preOne --(next)--> (3) preTwo --(next)--> (4) preThree --(next)--> (wait for dones to invoke) -> (5) doneTwo -> (6) doneOne -> (7) targetFn
+
+So what's happening is that:
+
+1. You call `doc.save(...)`
+2. First, your preOne middleware gets executed. It makes a remote call to the validation service and `next()`s to the preTwo middleware.
+3. Now, your preTwo middleware gets executed. It makes a remote call to another validation service and `next()`s to the preThree middleware.
+4. Your preThree middleware gets executed. It immediately `next()`s. But nothing else gets executing until both `doneOne` and `doneTwo` are invoked inside the callbacks handling the response from the two valiation services.
+5. We will suppose that validation remoteServiceTwo returns a response to us first. In this case, we call `doneTwo` inside the callback to remoteServiceTwo.
+6. Some fractions of a second later, remoteServiceOne returns a response to us. In this case, we call `doneOne` inside the callback to remoteServiceOne.
+7. `hooks` implementation keeps track of how many parallel middleware has been defined per target function. It detects that both asynchronous pre middlewares (`preOne` and `preTwo`) have finally called their `done` functions (`doneOne` and `doneTwo`), so the implementation finally invokes our `targetFn` (i.e., our core `save` business logic).
+
+## Removing Pres
+
+You can remove a particular pre associated with a hook:
+
+    Document.pre('set', someFn);
+    Document.removePre('set', someFn);
+
+And you can also remove all pres associated with a hook:
+    Document.removePre('set'); // Removes all declared `pre`s on the hook 'set'
+
+## Tests
+To run the tests:
+    make test

+## Contributing to the driver
+
+### Bugfixes
+
+- Before starting to write code, look for existing [tickets](https://github.com/mongodb/node-mongodb-native/issues) or [create one](https://github.com/mongodb/node-mongodb-native/issues/new) for your specific issue. That way you avoid working on something that might not be of interest or that has been addressed already in a different branch.
+- Fork the [repo](https://github.com/mongodb/node-mongodb-native) _or_ for small documentation changes, navigate to the source on github and click the [Edit](https://github.com/blog/844-forking-with-the-edit-button) button.
+- Follow the general coding style of the rest of the project:
+  - 2 space tabs
+  - no trailing whitespace
+  - comma last
+  - inline documentation for new methods, class members, etc
+  - 0 space between conditionals/functions, and their parenthesis and curly braces
+    - `if(..) {`
+    - `for(..) {`
+    - `while(..) {`
+    - `function(err) {`
+- Write tests and make sure they pass (execute `make test` from the cmd line to run the test suite).
+
+### Documentation
+
+To contribute to the [API documentation](http://mongodb.github.com/node-mongodb-native/) just make your changes to the inline documentation of the appropriate [source code](https://github.com/mongodb/node-mongodb-native/tree/master/docs) in the master branch and submit a [pull request](https://help.github.com/articles/using-pull-requests/). You might also use the github [Edit](https://github.com/blog/844-forking-with-the-edit-button) button.
+
+If you'd like to preview your documentation changes, first commit your changes to your local master branch, then execute `make generate_docs`. Make sure you have the python documentation framework sphinx installed `easy_install sphinx`. The docs are generated under `docs/build'. If all looks good, submit a [pull request](https://help.github.com/articles/using-pull-requests/) to the master branch with your changes.

+
+[Documentation](http://mongodb.github.com/node-mongodb-native/)
+
+Install
+=======
+
+To install the most recent release from npm, run:
+
+    npm install mongodb
+
+That may give you a warning telling you that bugs['web'] should be bugs['url'], it would be safe to ignore it (this has been fixed in the development version)
+
+To install the latest from the repository, run::
+
+    npm install path/to/node-mongodb-native
+
+Community
+=========
+Check out the google group [node-mongodb-native](http://groups.google.com/group/node-mongodb-native) for questions/answers from users of the driver.
+
+Live Examples
+============
+<a href="https://runnable.com/node-mongodb-native" target="_blank"><img src="https://runnable.com/external/styles/assets/runnablebtn.png" style="width:67px;height:25px;"></a>
+
+Introduction
+============
+
+This is a node.js driver for MongoDB. It's a port (or close to a port) of the library for ruby at http://github.com/mongodb/mongo-ruby-driver/.
+
+A simple example of inserting a document.
+
+```javascript
+  var MongoClient = require('mongodb').MongoClient
+    , format = require('util').format;    
+
+  MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) {
+    if(err) throw err;
+
+    var collection = db.collection('test_insert');
+    collection.insert({a:2}, function(err, docs) {
+      
+      collection.count(function(err, count) {
+        console.log(format("count = %s", count));
+      });
+
+      // Locate all the entries using find
+      collection.find().toArray(function(err, results) {
+        console.dir(results);
+        // Let's close the db
+        db.close();
+      });      
+    });
+  })
+```
+
+Data types
+==========
+
+To store and retrieve the non-JSON MongoDb primitives ([ObjectID](http://www.mongodb.org/display/DOCS/Object+IDs), Long, Binary, [Timestamp](http://www.mongodb.org/display/DOCS/Timestamp+data+type), [DBRef](http://www.mongodb.org/display/DOCS/Database+References#DatabaseReferences-DBRef), Code).
+
+In particular, every document has a unique `_id` which can be almost any type, and by default a 12-byte ObjectID is created. ObjectIDs can be represented as 24-digit hexadecimal strings, but you must convert the string back into an ObjectID before you can use it in the database. For example:
+
+```javascript
+  // Get the objectID type
+  var ObjectID = require('mongodb').ObjectID;
+
+  var idString = '4e4e1638c85e808431000003';
+  collection.findOne({_id: new ObjectID(idString)}, console.log)  // ok
+  collection.findOne({_id: idString}, console.log)  // wrong! callback gets undefined
+```
+
+Here are the constructors the non-Javascript BSON primitive types:
+
+```javascript
+  // Fetch the library
+  var mongo = require('mongodb');
+  // Create new instances of BSON types
+  new mongo.Long(numberString)
+  new mongo.ObjectID(hexString)
+  new mongo.Timestamp()  // the actual unique number is generated on insert.
+  new mongo.DBRef(collectionName, id, dbName)
+  new mongo.Binary(buffer)  // takes a string or Buffer
+  new mongo.Code(code, [context])
+  new mongo.Symbol(string)
+  new mongo.MinKey()
+  new mongo.MaxKey()
+  new mongo.Double(number)	// Force double storage
+```
+
+The C/C++ bson parser/serializer
+--------------------------------
+
+If you are running a version of this library has the C/C++ parser compiled, to enable the driver to use the C/C++ bson parser pass it the option native_parser:true like below
+
+```javascript
+  // using native_parser:
+  MongoClient.connect('mongodb://127.0.0.1:27017/test'
+    , {db: {native_parser: true}}, function(err, db) {})
+```
+
+The C++ parser uses the js objects both for serialization and deserialization.
+
+GitHub information
+==================
+
+The source code is available at http://github.com/mongodb/node-mongodb-native.
+You can either clone the repository or download a tarball of the latest release.
+
+Once you have the source you can test the driver by running
+
+    $ make test
+
+in the main directory. You will need to have a mongo instance running on localhost for the integration tests to pass.
+
+Examples
+========
+
+For examples look in the examples/ directory. You can execute the examples using node.
+
+    $ cd examples
+    $ node queries.js
+
+GridStore
+=========
+
+The GridStore class allows for storage of binary files in mongoDB using the mongoDB defined files and chunks collection definition.
+
+For more information have a look at [Gridstore](https://github.com/mongodb/node-mongodb-native/blob/master/docs/gridfs.md)
+
+Replicasets
+===========
+For more information about how to connect to a replicaset have a look at [Replicasets](https://github.com/mongodb/node-mongodb-native/blob/master/docs/replicaset.md)
+
+Primary Key Factories
+---------------------
+
+Defining your own primary key factory allows you to generate your own series of id's
+(this could f.ex be to use something like ISBN numbers). The generated the id needs to be a 12 byte long "string".
+
+Simple example below
+
+```javascript
+  var MongoClient = require('mongodb').MongoClient
+    , format = require('util').format;    
+
+  // Custom factory (need to provide a 12 byte array);
+  CustomPKFactory = function() {}
+  CustomPKFactory.prototype = new Object();
+  CustomPKFactory.createPk = function() {
+    return new ObjectID("aaaaaaaaaaaa");
+  }
+
+  MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) {
+    if(err) throw err;
+
+    db.dropDatabase(function(err, done) {
+      
+      db.createCollection('test_custom_key', function(err, collection) {
+        
+        collection.insert({'a':1}, function(err, docs) {
+          
+          collection.find({'_id':new ObjectID("aaaaaaaaaaaa")}).toArray(function(err, items) {
+            console.dir(items);
+            // Let's close the db
+            db.close();
+          });
+        });
+      });
+    });
+  });
+```
+
+Documentation
+=============
+
+If this document doesn't answer your questions, see the source of
+[Collection](https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/collection.js)
+or [Cursor](https://github.com/mongodb/node-mongodb-native/blob/master/lib/mongodb/cursor.js),
+or the documentation at MongoDB for query and update formats.
+
+Find
+----
+
+The find method is actually a factory method to create
+Cursor objects. A Cursor lazily uses the connection the first time
+you call `nextObject`, `each`, or `toArray`.
+
+The basic operation on a cursor is the `nextObject` method
+that fetches the next matching document from the database. The convenience
+methods `each` and `toArray` call `nextObject` until the cursor is exhausted.
+
+Signatures:
+
+```javascript
+  var cursor = collection.find(query, [fields], options);
+  cursor.sort(fields).limit(n).skip(m).
+
+  cursor.nextObject(function(err, doc) {});
+  cursor.each(function(err, doc) {});
+  cursor.toArray(function(err, docs) {});
+
+  cursor.rewind()  // reset the cursor to its initial state.
+```
+
+Useful chainable methods of cursor. These can optionally be options of `find` instead of method calls:
+
+  * `.limit(n).skip(m)` to control paging.
+  * `.sort(fields)` Order by the given fields. There are several equivalent syntaxes:
+  * `.sort({field1: -1, field2: 1})` descending by field1, then ascending by field2.
+  * `.sort([['field1', 'desc'], ['field2', 'asc']])` same as above
+  * `.sort([['field1', 'desc'], 'field2'])` same as above
+  * `.sort('field1')` ascending by field1
+
+Other options of `find`:
+
+* `fields` the fields to fetch (to avoid transferring the entire document)
+* `tailable` if true, makes the cursor [tailable](http://www.mongodb.org/display/DOCS/Tailable+Cursors).
+* `batchSize` The number of the subset of results to request the database
+to return for every request. This should initially be greater than 1 otherwise
+the database will automatically close the cursor. The batch size can be set to 1
+with `batchSize(n, function(err){})` after performing the initial query to the database.
+* `hint` See [Optimization: hint](http://www.mongodb.org/display/DOCS/Optimization#Optimization-Hint).
+* `explain` turns this into an explain query. You can also call
+`explain()` on any cursor to fetch the explanation.
+* `snapshot` prevents documents that are updated while the query is active
+from being returned multiple times. See more
+[details about query snapshots](http://www.mongodb.org/display/DOCS/How+to+do+Snapshotted+Queries+in+the+Mongo+Database).
+* `timeout` if false, asks MongoDb not to time out this cursor after an
+inactivity period.
+
+
+For information on how to create queries, see the
+[MongoDB section on querying](http://www.mongodb.org/display/DOCS/Querying).
+
+```javascript
+  var MongoClient = require('mongodb').MongoClient
+    , format = require('util').format;    
+
+  MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) {
+    if(err) throw err;
+
+    var collection = db
+      .collection('test')
+      .find({})
+      .limit(10)
+      .toArray(function(err, docs) {
+        console.dir(docs);
+    });
+  });
+```
+
+Insert
+------
+
+Signature:
+
+```javascript
+  collection.insert(docs, options, [callback]);
+```
+
+where `docs` can be a single document or an array of documents.
+
+Useful options:
+
+* `safe:true` Should always set if you have a callback.
+
+See also: [MongoDB docs for insert](http://www.mongodb.org/display/DOCS/Inserting).
+
+```javascript
+  var MongoClient = require('mongodb').MongoClient
+    , format = require('util').format;    
+
+  MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) {
+    if(err) throw err;
+    
+    db.collection('test').insert({hello: 'world'}, {w:1}, function(err, objects) {
+      if (err) console.warn(err.message);
+      if (err && err.message.indexOf('E11000 ') !== -1) {
+        // this _id was already inserted in the database
+      }
+    });
+  });
+```
+
+Note that there's no reason to pass a callback to the insert or update commands
+unless you use the `safe:true` option. If you don't specify `safe:true`, then
+your callback will be called immediately.
+
+Update; update and insert (upsert)
+----------------------------------
+
+The update operation will update the first document that matches your query
+(or all documents that match if you use `multi:true`).
+If `safe:true`, `upsert` is not set, and no documents match, your callback will return 0 documents updated.
+
+See the [MongoDB docs](http://www.mongodb.org/display/DOCS/Updating) for
+the modifier (`$inc`, `$set`, `$push`, etc.) formats.
+
+Signature:
+
+```javascript
+  collection.update(criteria, objNew, options, [callback]);
+```
+
+Useful options:
+
+* `safe:true` Should always set if you have a callback.
+* `multi:true` If set, all matching documents are updated, not just the first.
+* `upsert:true` Atomically inserts the document if no documents matched.
+
+Example for `update`:
+
+```javascript
+  var MongoClient = require('mongodb').MongoClient
+    , format = require('util').format;    
+
+  MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) {
+    if(err) throw err;
+
+    db.collection('test').update({hi: 'here'}, {$set: {hi: 'there'}}, {w:1}, function(err) {
+      if (err) console.warn(err.message);
+      else console.log('successfully updated');
+    });
+  });
+```
+
+Find and modify
+---------------
+
+`findAndModify` is like `update`, but it also gives the updated document to
+your callback. But there are a few key differences between findAndModify and
+update:
+
+  1. The signatures differ.
+  2. You can only findAndModify a single item, not multiple items.
+
+Signature:
+
+```javascript
+    collection.findAndModify(query, sort, update, options, callback)
+```
+
+The sort parameter is used to specify which object to operate on, if more than
+one document matches. It takes the same format as the cursor sort (see
+Connection.find above).
+
+See the
+[MongoDB docs for findAndModify](http://www.mongodb.org/display/DOCS/findAndModify+Command)
+for more details.
+
+Useful options:
+
+* `remove:true` set to a true to remove the object before returning
+* `new:true` set to true if you want to return the modified object rather than the original. Ignored for remove.
+* `upsert:true` Atomically inserts the document if no documents matched.
+
+Example for `findAndModify`:
+
+```javascript
+  var MongoClient = require('mongodb').MongoClient
+    , format = require('util').format;    
+
+  MongoClient.connect('mongodb://127.0.0.1:27017/test', function(err, db) {
+    if(err) throw err;
+    db.collection('test').findAndModify({hello: 'world'}, [['_id','asc']], {$set: {hi: 'there'}}, {}, function(err, object) {
+      if (err) console.warn(err.message);
+      else console.dir(object);  // undefined if no matching object exists.
+    });
+  });
+```
+
+Save
+----
+
+The `save` method is a shorthand for upsert if the document contains an
+`_id`, or an insert if there is no `_id`.
+
+Sponsors
+========
+Just as Felix Geisendörfer I'm also working on the driver for my own startup and this driver is a big project that also benefits other companies who are using MongoDB.
+
+If your company could benefit from a even better-engineered node.js mongodb driver I would appreciate any type of sponsorship you may be able to provide. All the sponsors will get a lifetime display in this readme, priority support and help on problems and votes on the roadmap decisions for the driver. If you are interested contact me on [christkv AT g m a i l.com](mailto:christkv@gmail.com) for details.
+
+And I'm very thankful for code contributions. If you are interested in working on features please contact me so we can discuss API design and testing.
