Hello there, it's me again responding a question that arrived via email:

We are still developing the documentation for Admin Panel Pro, so I'm sorry for that.

Once installed Admin Panel Pro, you have to do this:

1. Set-up your license key so you can perform automatic updates
2. Create a menu item for the panel
3. Create a super user account in the panel back-end
4. Log-in to your admin panel (in the front-end)

Tell me if you need any further information
