 ## Installation
 
+Obtain the .jsonc files from the release tab. If you want to recompile the asset files in order to add your own color overrides, please check the "Compiling" section.
+
 Copy the Jsonc theme files you want into your GitKraken Theme directory, and Voila ! the themes are availablie in the preferences.
 
 _You can find your GitKraken Theme directory by going into your GitKraken Preferences in the UI Customization menu, on Windows it usually is `%appdata%/.gitkraken/themes`_
+
+## Compiling
+
+This project uses the [Whiskers](https://github.com/catppuccin/whiskers) templating engine starting from 1.0.0. This enables you to add your own color overrides if needed.
+
+To reprocess the jsonc files :
+
+- Download and install [Whiskers](https://github.com/catppuccin/whiskers)
+- Download this project and unzip it somewhere
+- Run `whiskers gitkraken.tera`
+
+Once this is done, the jsonc files in the `./themes` folder will be ready to be used as described in section "Installation"
