+## 🔥 Contributing
+
+Pull requests are welcome. For the `extras`, we use a simple template system that can be used to generate themes for the different styles.
+
+How to add a new extra template:
+
+1. create a file like `lua/tokyonight/extra/cool-app.lua`
+2. add the name and output file extension to the `extras` table in `lua/tokyonight/extra/init.lua`
+3. in the root directory, run `$ lua lua/tokyonight/extra/init.lua` to generate / update extra themes
+4. commit the newly created themes under `extra/`
