+Minetest Mod - Simple Shooter [shooter]
+=======================================
+
+Mod Version: 0.1.0
+
+Minetest Version: 0.4.8
+
+Depends: default
+
+An experimental first person shooter mod using vector mathematics instead of
+physical projectile entities. This has a number of advantages along with a
+number disadvantages.
+
+Pros:
+
+Fast and responsive
+Fairly light weight
+Not affected by chunk boundaries
+
+Cons:
+
+Only works against other players
+Slightly less realistic
+
+This is still very much a work in progress and currently not much use in a
+singleplayer game. I plan to eventually use this as a base for a 'Spades' style
+FPS game using the minetest engine, however, I decided to add a couple of craft
+recipes and release this simple version for minetest_game.
+
+Crafting
+========
+
+S = Steel Ingot  [default:steel_ingot]
+B = Bronze Ingot [default:bronze_ingot]
+M = Mese Crystal [default:mese_crysytal]
+
+Pistol: [shooter:pistol]
