+# Themes (WIP)
+
+## Making a theme
+* If one does not already exist, create a new theme directory in the user data folder.
+  * **Windows:** `%appdata%/Cider/themes`
+  * **Mac:** `~/Library/Application Support/Cider/themes`
+  * **Linux:** `~/.config/Cider/themes`
+* Create a `theme.less` file with the name of the theme.
+* In Cider, select the theme in the settings.
+* To enable hot reloading for the theme, open the DevTools and enter `less.watch()` in the console.
+
+## Resources
+* The default styles.less can be found in: [src/renderer/style.less](https://github.com/ciderapp/Cider/tree/main/src/renderer/style.less)
+* [Less.js documentation](https://lesscss.org/)
