+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
+Craft gunpowder by placing coal and gravel in the crafting area.
-surround gunpowder with 4 wood in a + shape.
+The gunpowder can be used to craft TNT sticks or as a fuse trail for TNT.
-There are different ways to blow up TNT:
+
+To craft 2 TNT sticks:
+G_G
+GPG
+G_G
+G = gunpowder
+P = paper
+The sticks are not usable as an explosive.
+
+Craft TNT from 9 TNT sticks.
+
+There are different ways to ignite TNT:
   1. Hit it with a torch.
-  2. Hit a gunpowder fuze that leads to a TNT block with a torch.
+  2. Hit a gunpowder fuse trail that leads to TNT with a torch or
-  3. Activate it with mesecons (fastest way)
+     flint-and-steel.
-Be aware of the damage radius of 7 blocks!
+  3. Activate it with mesecons (fastest way).
 
-License:
+For 1 TNT:
-WTFPL (see below)
+Node destruction radius is 3 nodes.
-
+Player and object damage radius is 6 nodes.
