+Playing around with [Love 2D](https://www.love2d.org/), [Lua](https://www.lua.org/),
+and [Fennel](https://fennel-lang.org/).
 
 ## Dev
 
+### Init
+
 Follow steps at [here](https://love2d.org/wiki/Getting_Started)
 to download, install, and add Love 2d to path.
 
 Once done games can be started with `love ./game_dir`
+
+### Dir setup
+
+Fennel setup copied from [~benthor/absolutely-minimal-love2d-fennel](https://git.sr.ht/~benthor/absolutely-minimal-love2d-fennel/tree/master/item/README.md).
+Since fennel.lua and main.lua are the same for each game/project I put them on root level and soft linked to them
+in the project folders.
