+What is it?
+
+In essense, this plugin allows for multiple users across multiple servers to use one RainLoop installation,
+all without the administrator needing to create each domain separately. This plugin detects the required
+hostname from the inputted email address (for example, it would detect "example.com" as the hostname if
+"info@example.com" is inputted). This hostname is then used for IMAP and SMTP communication.
+
+How to Use:
+
+1) Activate plugin
+2) Visit Settings, and add a new wildcard domain ' * '
+3) Set your ports/ssl requirements as needed. These will not be changed by the plugin.
+4) In the SMTP and/or IMAP host fields, place the single word "auto". This will be replaced when the plugin is active.
+5) That's it! The plugin should now work!
