+[![Build Status](https://travis-ci.org/firebase/php-jwt.png?branch=master)](https://travis-ci.org/firebase/php-jwt)
+
+PHP-JWT
+=======
+A simple library to encode and decode JSON Web Tokens (JWT) in PHP. Should
+conform to the [current spec](http://tools.ietf.org/html/draft-ietf-oauth-json-web-token-06)
+
+Installation
+------------
+
+Use composer to manage your dependencies and download PHP-JWT:
+
+```bash
+composer require firebase/php-jwt
+```
+
+Example
+-------
+```php
+<?php
+
+$key = "example_key";
+$token = array(
+    "iss" => "http://example.org",
+    "aud" => "http://example.com",
+    "iat" => 1356999524,
+    "nbf" => 1357000000
+);
+
+/**
+ * IMPORTANT:
+ * You must specify supported algorithms for your application. See
+ * https://tools.ietf.org/html/draft-ietf-jose-json-web-algorithms-40
+ * for a list of spec-compliant algorithms.
+ */
+$jwt = JWT::encode($token, $key);
+$decoded = JWT::decode($jwt, $key, array('HS256'));
+
+print_r($decoded);
+
+/*
+ NOTE: This will now be an object instead of an associative array. To get
+ an associative array, you will need to cast it as such:
+*/
+
+$decoded_array = (array) $decoded;
+
+/**
+ * You can add a leeway to account for when there is a clock skew times between
+ * the signing and verifying servers. It is recommended that this leeway should
+ * not be bigger than a few minutes.
+ *
+ * Source: http://self-issued.info/docs/draft-ietf-oauth-json-web-token.html#nbfDef
+ */
+JWT::$leeway = 60; // $leeway in seconds
+$decoded = JWT::decode($jwt, $key, array('HS256'));
+
+?>
+```
+
+Changelog
+---------
+
+#### 2.1.0 / 2015-05-20
+- Add support for adding a leeway to `JWT:decode()` that accounts for clock skew
+between signing and verifying entities. Thanks to [@lcabral](https://github.com/lcabral)!
+- Add support for passing an object implementing the `ArrayAccess` interface for
+`$keys` argument in `JWT::decode()`. Thanks to [@aztech-dev](https://github.com/aztech-dev)!
+
+#### 2.0.0 / 2015-04-01
+- **Note**: It is strongly recommended that you update to > v2.0.0 to address
+  known security vulnerabilities in prior versions when both symmetric and
+  asymmetric keys are used together.
+- Update signature for `JWT::decode(...)` to require an array of supported
+  algorithms to use when verifying token signatures.
+
+
