The Shallows
Start near the surface. Modify the .yaml GUI files located in your server's plugins/ClanSystem/inventories/saver/ folder. Customize glass colors, slots, and items. Test it live in Minecraft to ensure your UI looks stunning.
The Drop-off
Fork the CDN repository. Create a new folder with your theme's name in lowercase (e.g., deep-blue). Create two subfolders: configs/ and inventories/ and place your custom files there.
The Twilight Zone
Create a theme.json in your theme's root folder. This manifest acts as your sonar, telling the plugin exactly which files to download and hot-reload.
The Ocean Floor
Finally, register your theme by adding its metadata to the central registry at v1/templates/themes.json. Commit your treasures and open a Pull Request on GitHub!
