 ## What is `level`?
 `level` is a tool for reskit that converts [Tiled Map Editor](https://www.mapeditor.org/) tilesets and maps to a binary format accessible to C or assembly language engines. It distinguishes itself from other available homebrew tools by offering support for Tiled's native tmx/tsx XML formats, and user-specified entity-component system definitions.
 
+## Tilesets and Maps
+To convert a Tiled map and tileset:
+```
+reskit level -i map.tmx -c mapping.toml
+```
+Reskit will compile and output a .lvl file which you can then bundle into your game project. (More information on .lvl format TBD)
+
 ## Entity-Component System
 Reskit assumes a best-practice entity-component engine design and the objects defined in your .tmx file effectively serve as the entities.
