+## Editing Levels
+
+Generally creating a level looks like:
+
+```
+SVG File -> Custom Level File -> Game
+```
+
+To convert SVG to the level file install [xqilla] and run
+[svg2rects.xqe] script:
+
+```console
+$ xqilla ./devtools/svg2rects.xqe -i <svg-file> -o <level-file>
+```
+
+All of the levels reside in the [./levels/] folder. Use
+[./levels/Makefile] to automatically rebuild all levels.
+
+### Level Editing Workflow
+
+1. `$ inkscape ./levels/level.svg &`
+2. `$ ./build/nothing ./levels/level.txt &`
+3. `$ cd ./levels/`
+4. `$ make watch`
+5. Edit Level in Inkscape and Save
+6. Switch to the Game and reload level by pressing Q
+7. Go to 5
