improve description

the server now utilizes the velocity proxy for
- domain based connection instead of ports (called forced-hosts in velocity)
- a fancy motd message indicating when only the minecraft server is down, but not the host system

 ## About MMS
 
-This is a **M**odded **M**inecraft **S**erver project, mostly a modpack. (please tell me a better name than MMS, I'm open for suggestions)  
+**M**odded **M**inecraft **S**erver project - the name says it all (I'm open for suggestions if you've got a better name). This repository is mostly about the modpack and includes other info like the configuration of the official server running at mms.nanody.de.  
-MMS is centralised around the [Create mod](https://github.com/Fabricators-of-Create/Create). Why Create? Because it's a cool mod, obviously!  
+MMS revolves around the [Create mod](https://github.com/Fabricators-of-Create/Create). Why Create? Because it's a cool mod, obviously!  
 Apart from that there are 4 goals:  
 - Only add features and functionality to the game, keep the vanilla features and functionality untouched. Complex Redstone contraptions, for example, which are supposed to work in vanilla, should also work with the MMS modpack.  
 - Find a middle ground between being too minimalistic and too bloated.
