+=== TNT-MOD for MINETEST-C55 ===
+by PilzAdam
+
+Introduction:
+This mod adds TNT to Minetest. TNT is a tool to help the player
+in mining.
+
+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:
+Craft gunpowder by placing coal and gravel in the crafting area. The
+gunpowder can be used to craft TNT or as fuze for TNT. To craft TNT
+surround gunpowder with 4 wood in a + shape.
+There are different ways to blow up TNT:
+1. Hit it with a torch.
+2. Hit a gunpowder fuze that leads to a TNT block with a torch.
+3. Activate it with mesecons (fastest way)
+Be aware of the damage radius of 7 blocks!
