A dark, GitHub-style theme for Garry's Mod: main menu, server browser, addon manager, map selection and the Derma spawn menu — restyled as a single drop-in addon. Based on JWalkerMailly/Derma-Github-Theme.
- Dark GitHub-style palette across the whole menu UI
- Menu files load from the addon folder — game updates and Steam file verification don't wipe the theme
- Server browser synced with the current in-game browser: infinite scroll, double-click to join, country flags, version tags, favorites by IP
- Addon manager with preset import/export, multi-select enable/disable and dependency warnings
- Settings gear in the navbar: UI scale (75–135%) and an optional "apply theme to all gamemodes"
- Close Garry's Mod.
- Copy this folder into
.../Steam/steamapps/common/GarrysMod/garrysmod/addons/ - Start the game.
If you previously installed a version by copying files into garrysmod/html, run Steam's "Verify integrity of game files" once to restore the originals — the addon overrides them anyway.
Open the gear icon in the bottom-right of the main menu:
- UI Scale — minus / current value (click to reset) / plus, 75–135%.
- Apply theme to all gamemodes — off by default; Takes effect on the next game load.
Both settings persist between sessions.
- Base project: JWalkerMailly/Derma-Github-Theme
- Menu icons: Octicons by GitHub
