+This plugin depends on the OpenProject Plugins plugin, so insert it into your `Gemfile.plugins` before the auth_plugins plugin itself:
 
     gem "openproject-plugins", :git => "git@github.com:opf/openproject-plugins.git", :branch => "dev"
 
 ## Usage
 
+    gem "openproject-auth_plugins", :git => 'git@github.com:finnlabs/openproject-auth_plugins, :branch => "dev"
+
 You can use this plugin to make an authentication plugin out of an ordinary OpenProject plugin.
 The first step is to [generate a new plugin](https://github.com/opf/openproject-plugins#generator) using the Plugins plugin.
 Once you have done that it only takes a few additions to make it an authentication plugin.
