+## Dependencies
+
+- [gcc]
+- [cmake]
+- [libsdl2-dev]
+- [libsdl2-mixer-dev]
+- [xqilla]
+- [inotify-tools]
+
+### Ubuntu
+
+```console
+$ sudo apt-get install gcc cmake libsdl2-dev libsdl2-mixer-dev xqilla inotify-tools
+```
+### NixOS
+
+For [NixOS] we have a development environment defined in [default.nix]
+with all of the required dependencies. You can enter the environment
+`nix-shell` command:
+
+```console
+$ nix-shell
+```
+
+### Windows
+
+See [Build on Windows][build-on-windows] section.
 
 ## Quick Start
 
 ```console
-$ nix-shell              # Only on NixOS
 $ mkdir build
 $ cd build/
 $ cmake ..
 $ make
-$ ./nothing <level-file>
+$ ./nothing ../levels/level-01.txt
+$ ./nothing_test
 ```

+
+## 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
