 The Github authentication in Kanboard uses the [OAuth 2.0](http://oauth.net/2/) protocol, so any user of Kanboard can be linked to a Github account.
 
-When that is done, they no longer need to manually login with their Kanboard account, but can simply automatically login with their Github account.
+That means you can use your Github account to connect to Kanboard.

+### Github Entreprise
+
+To use this authentication method with Github Enterprise you have to change the default urls.
+
+Replace these values by your self-hosted instance of Github:
+
+```php
+// Github oauth2 authorize url
+define('GITHUB_OAUTH_AUTHORIZE_URL', 'https://github.com/login/oauth/authorize');
+
