+=== MOBS-MOD for MINETEST-C55 ===
+by PilzAdam
+
+Inroduction:
+This mod adds some basic hostile and friendly mobs to the game.
+
+How to install:
+Unzip the archive an place it in minetest-base-directory/mods/minetest/
+if you have a windows client or a linux run-in-place client. If you have
+a linux system-wide instalation place it in ~/.minetest/mods/minetest/.
+If you want to install this mod only in one world create the folder
+worldmods/ in your worlddirectory.
+For further information or help see:
+http://wiki.minetest.com/wiki/Installing_Mods
+
+How to use the mod:
+See https://github.com/PilzAdam/mobs/wiki
+
+For developers:
