 ## MMS - Description
 
-a **M**odded **M**inecraft **S**erver project - modpack development & more  
-This is a project centralised around the Create mod.
+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)  
+The modpack is centralised around the Create mod. 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.  
+- Improve performance and be playable on inexpensive hardware.  
+- Prefer open source software and respect user privacy by default.  
+Based on those goals everything else is decided.  
+That's why the mod loader is [Fabric](https://fabricmc.net/), which is lightweight and doesn't change Minecraft's vanilla behaviour.  
+
+The 'modpack' is actually separated into two modpacks: MMS-client and MMS-server. The later is supposed to run on a server, the first is supposed to run on a client and connect to the server.  
+Additionally, MMS-minimum is provided as information on how to make a client compatible with the server. It's only the bare minimum to achieve compatibility. It also includes optional mods, which the server provides supports for. They are `.disabled` by default.

+This is the Git repository of MMS. This repositry's goal is to ease development of the project with the Git workflow, enable collaboration (in the future) and of course to make the project [open source](https://en.wikipedia.org/wiki/Open_source).
