 # Cave Game
 A recreation of Cave Game, the earliest version of Minecraft.
 
+## Features
+- Stone and grass nodes.
+- Place & destroy them.
+- That's about it.
+
+## Notes
+
+Whilst looking like cobble, stone is infact `minecraft:stone`.
+
+Technical names `minecraft:nnn` and `nnn` are aliases to the "modern" Minecraft names.
+
+Select mapgen `singlenode` for a truly flat world.
+Mapgen v6 unsupported.
