+
+## Install

+    $ npm install jwt-simple
+
+## Usage
+
+```javascript
+var jwt = require('jwt-simple');
+var payload = { foo: 'bar' };
+var secret = 'xxx';
+
+// encode
+var token = jwt.encode(payload, secret);
+
+// decode
+var decoded = jwt.decode(token, secret);
+console.log(decoded); //=> { foo: 'bar' }
+```
+
+### Algorithms
+
+By default the algorithm to encode is `HS256`.
+
+The supported algorithms for encoding and decoding are `HS256`, `HS384`, `HS512` and `RS256`.
+
+```javascript
+// encode using HS512
+jwt.encode(payload, secret, 'HS512')
+```
