 yourls-authmgr-plugin
 =====================
 
-This plugin adds role-based access controls (RBAC) to YOURLS.
+This plugin adds role-based access controls (RBAC) to YOURLS. By assigning users to roles like "Editor" and "Contributor" you can limit the changes they are permitted to make.
+
+With access controls enabled, you can safely delegate access to the admin pages.
+
+Installation
+------------
+1. Download the [latest release](https://github.com/nicwaller/yourls-authmgr-plugin/tags) of yourls-authmgr-plugin.
+1. Copy the plugin folder into your `user/plugins` folder for YOURLS.
+1. Set up the parameters for authmgr (details below)
+1. Activate the plugin with the plugin manager in the YOURLS admin interface.
+
+Default Roles
+-------------
+The default roles are set up as follows:
+
+* Administrator : No limits
+* Editor : Cannot manage plugins
+* Contributor : Cannot manage plugins, edit URLS, or delete URLs
+
+Configuration
+-------------
+Add role assignments to your `user/config.php` file.
+
+```
+$authmgr_role_assignment = array(
+  'administrator' => array(
+    'your_username',
+  ),
+  'editor' => array(
+    'your_close_friend',
+  ),
+  'contributor' => array(
+    'your_other_friend',
+  ),
+);
+```
+
+You can also designate a range of IP addresses that will automatically be granted all capabilities. By default, all accesses from IPv4 localhost (127.0.0.0/8) are granted full access.
+
+```
+$authmgr_admin_ipranges = array(
+    '127.0.0.0/8',
+);
+```
