+# Passport-Google-OAuth
+
+[Passport](http://passportjs.org/) strategies for authenticating with [Google](http://www.google.com/)
+using OAuth 1.0a and OAuth 2.0.
+
+This module lets you authenticate using Google in your Node.js applications.
+By plugging into Passport, Google authentication can be easily and
+unobtrusively integrated into any application or framework that supports
+[Connect](http://www.senchalabs.org/connect/)-style middleware, including
+[Express](http://expressjs.com/).
+
+## Install
+
+    $ npm install passport-google-oauth
+
+## Usage of OAuth 1.0
+
+#### Configure Strategy
+
+The Google OAuth 1.0 authentication strategy authenticates users using a Google
+account and OAuth tokens.  The strategy requires a `verify` callback, which
+accepts these credentials and calls `done` providing a user, as well as `options`
+specifying a consumer key, consumer secret, and callback URL.
+
+    passport.use(new GoogleStrategy({
+        consumerKey: GOOGLE_CONSUMER_KEY,
+        consumerSecret: GOOGLE_CONSUMER_SECRET,
+        callbackURL: "http://127.0.0.1:3000/auth/google/callback"
+      },
+      function(token, tokenSecret, profile, done) {
+        User.findOrCreate({ googleId: profile.id }, function (err, user) {
+          return done(err, user);
+        });
+      }
+    ));
+
+#### Authenticate Requests
+
+Use `passport.authenticate()`, specifying the `'google'` strategy, to
+authenticate requests.
+
+For example, as route middleware in an [Express](http://expressjs.com/)
+application:
+
+    app.get('/auth/google',
+      passport.authenticate('google', { scope: 'https://www.google.com/m8/feeds' }));
+
+    app.get('/auth/google/callback', 
+      passport.authenticate('google', { failureRedirect: '/login' }),
+      function(req, res) {
+        // Successful authentication, redirect home.
+        res.redirect('/');
+      });
+
+## Usage of OAuth 2.0
+
+#### Configure Strategy
+
+The Google OAuth 2.0 authentication strategy authenticates users using a Google
+account and OAuth 2.0 tokens.  The strategy requires a `verify` callback, which
+accepts these credentials and calls `done` providing a user, as well as
+`options` specifying a client ID, client secret, and callback URL.
+
+    passport.use(new GoogleStrategy({
+        clientID: GOOGLE_CLIENT_ID,
+        clientSecret: GOOGLE_CLIENT_SECRET,
+        callbackURL: "http://127.0.0.1:3000/auth/google/callback"
+      },
+      function(accessToken, refreshToken, profile, done) {
+        User.findOrCreate({ googleId: profile.id }, function (err, user) {
+          return done(err, user);
+        });
+      }
+    ));
+
+#### Authenticate Requests
+
+Use `passport.authenticate()`, specifying the `'google'` strategy, to
+authenticate requests.
+
+For example, as route middleware in an [Express](http://expressjs.com/)
+application:
+
+    app.get('/auth/google',
+      passport.authenticate('google'));
+
+    app.get('/auth/google/callback', 
+      passport.authenticate('google', { failureRedirect: '/login' }),
+      function(req, res) {
+        // Successful authentication, redirect home.
+        res.redirect('/');
+      });
