 Minetest Game mod: tnt
 ======================
-by PilzAdam and ShadowNinja
+See license.txt for license information.
 
-Introduction:
-This mod adds TNT to Minetest. TNT is a tool to help the player
-in mining.
-
-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!
