 ## Converting a Tiled Map Editor Module with `level`
 To convert a Tiled map and tileset:
 ```
-reskit level -i map.tmx -c mapping.toml --tile-size-pixels 16x16
+reskit level -i map.tmx -c mapping.toml --system md --tile-size 2x2
 ```
 Reskit will compile and output a .lvl file which you can then bundle into your game project. (More information on .lvl format TBD)
