Clear up maubot role (#1960)

* Make interface hidden behind proxy by default

* Remove expose option and replace with http_bind_port

Reasoning: This is a similar binary trigger but allows to bin not on all interfaces

* Clarify maubot admin purpose

* Remove unnecessary edif

* Extend docs to prevent common misconceptions

* Make http_bind_port singular, do not allow multiple values

* Make optional again

 ## Usage
 
 You can visit `matrix.<your-domain>/_matrix/maubot/` to manage your available plugins, clients and instances.
+
+You should start in the following order
+1. **Create one or more clients:** A client is a matrix account which the bot will use to message.
+2. **Upload some Plugins:** Plugins can be obtained from [here](https://github.com/maubot/maubot#plugins) or any other source.
+3. **Create an instance:** An instance is the actual bot. You have to specify a client which the bot instance will use 
+and the plugin (how the bot will behave)
+
 To add a client you first need to create an account and obtain a valid access token.
