 ## minetest-git
 minetest-git is a Dockerfile to build a minetestserver from git.
-
+This conflicts zombi/minetest on Port 30000. If you want to run both,
+make sure to let one of it use a different port. It will also use a
+present default world at /data/minetest. The World might become
+uncompatible with older (stable) Versions of minetest.
