 Config for [LeftWM](https://github.com/leftwm/leftwm), a window manager written in rust. The current config contains basic keybindings and workspace specified for few apps. Gaps, colors, themes, etc., are not configured yet.  
 Config location: `~/.config/leftwm/config.ron`  
+
+## Theme config  
+
+The scripts and config files for the theme must be in a directory sym-linked to `~/.config/leftwm/themes/current/`.  
+Minimum required files:  
+- `theme.ron`: LeftWM theme config including border color, margins, etc.  
+- `up`: This script is called on login. The `theme.ron` must be loaded by this script using LeftWM's `LoadTheme` command:  
+```bash
+leftwm command "LoadTheme ~/.config/leftwm/themes/current/theme.ron"
+```  
+  Add lines to load other theme elements like `eww daemon`, `polybar`, or anything you have configured for your desktop.  
+- `down`: To unload the theme.
