-# The League of Extraordinary Packages presents: PHP OAuth 2.0 Server

-The goal of this project is to develop a standards compliant [OAuth 2.0](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-v2/) authorization server and resource server.

-## Package Installation
 
-The framework is provided as a Composer package which can be installed by adding the package to your composer.json file:
+A standards compliant [OAuth 2.0](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-v2/) authorization server and resource server written in PHP which makes working with OAuth 2.0 trivial. You can easily configure an OAuth 2.0 server to protect your API with access tokens, or allow clients to request new access tokens and refresh them.
 
-```javascript
-{
-	"require": {
-		"league/oauth2-server": "2.*"
-	}
-}
-```
+It supports out of the box the following grants:
 
----
+* Authorization code grant
+* Client credentials grant
+* Resource owner password credentials grant
+* Refresh grant
 
-The library features 100% unit test code coverage. To run the tests yourself run `phpunit` from the project root.
+You can also define your own grants.
 
-## Current Features
+In addition it supports the following token types:
 
-### Authorization Server
+* Bearer tokens
+* MAC tokens
+* JSON web tokens (coming soon)
 
-The authorization server is a flexible class and the following core specification grants are implemented:
+You can also create you own tokens.
 
-* authorization code ([section 4.1](http://tools.ietf.org/html/rfc6749#section-4.1))
-* refresh token ([section 6](http://tools.ietf.org/html/rfc6749#section-6))
-* client credentials ([section 2.3.1](http://tools.ietf.org/html/rfc6749#section-2.3.1))
-* password (user credentials) ([section 4.3](http://tools.ietf.org/html/rfc6749#section-4.3))
 
-An overview of the different OAuth 2.0 grants can be found in the wiki [https://github.com/php-loep/oauth2-server/wiki/Which-OAuth-2.0-grant-should-I-use%3F](https://github.com/php-loep/oauth2-server/wiki/Which-OAuth-2.0-grant-should-I-use%3F).
+## Requirements
 
-### Resource Server
+The following versions of PHP are supported:
 
-The resource server allows you to secure your API endpoints by checking for a valid OAuth access token in the request and ensuring the token has the correct scope(s) (i.e. permissions) to access resources.
+* PHP 5.4
+* PHP 5.5
+* PHP 5.6
+* HHVM
 
-### Custom grants
+## Documentation
 
-Custom grants can be created easily by implementing an interface. Check out a guide here [https://github.com/php-loep/oauth2-server/wiki/Creating-custom-grants](https://github.com/php-loep/oauth2-server/wiki/Creating-custom-grants).
+This library has [full documentation](http://oauth2.thephpleague.com), powered by [Jekyll](http://jekyllrb.com/).
 
-### PDO driver
+Contribute to this documentation in the [gh-pages branch](https://github.com/thephpleague/oauth2-server/tree/gh-pages/).
 
-If you are using MySQL and want to very quickly implement the library then all of the storage interfaces have been implemented with PDO classes. Check out the guide here [https://github.com/php-loep/oauth2-server/wiki/Using-the-PDO-storage-classes](https://github.com/php-loep/oauth2-server/wiki/Using-the-PDO-storage-classes).
+## Changelog
 
-## Tutorials and documentation
+[See the project releases page](https://github.com/thephpleague/oauth2-server/releases)
 
-The wiki has lots of guides on how to use this library, check it out - [https://github.com/php-loep/oauth2-server/wiki](https://github.com/php-loep/oauth2-server/wiki).
+## Contributing
 
-A tutorial on how to use the authorization server can be found on the wiki - (https://github.com/php-loep/oauth2-server/wiki/Developing-an-OAuth-2.0-authorization-server)[https://github.com/php-loep/oauth2-server/wiki/Developing-an-OAuth-2.0-authorization-server].
+Please see [CONTRIBUTING](https://github.com/thephpleague/oauth2-server/blob/master/CONTRIBUTING.md) for details.
 
-A tutorial on how to use the resource server to secure an API server can be found at [https://github.com/php-loep/oauth2-server/wiki/Securing-your-API-with-OAuth-2.0](https://github.com/php-loep/oauth2-server/wiki/Securing-your-API-with-OAuth-2.0).
+## Support
 
-## Future Goals
+Bugs and feature request are tracked on [GitHub](https://github.com/thephpleague/oauth2-server/issues)
 
-### Authorization Server
+## License
 
-* Support for [JSON web tokens](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-json-web-token/).
-* Support for [SAML assertions](http://tools.ietf.org/wg/oauth/draft-ietf-oauth-saml2-bearer/).
