+# gitea-github-theme
+Opinionated GitHub-based light and dark themes for Gitea
+
+Created and tested with Gitea v1.15.
+The theme might work with future versions though Gitea devs might change some CSS classes in the meantime and things might potentially look odd - just try yourself :)
+
+I might update the theme over time to fix oversights and other issues - no guarantee though.
+## Installation
+
+1. If you do not have admin access to a Gitea instance, you can use the [Stylus](https://chrome.google.com/webstore/detail/stylus/clngdbkpkpeebahjckkjfobafhncgmne/related) browser extension and use the CSS provided in this repo for the Gitea URL
+2. If you are an admin and want to make this theme available to all users:
+   1. Put `theme-github.css` into `$GITEA_PUBLIC/public/css/theme-github.css` where `$GITEA_PUBLIC` is the "CustomPath" of your instance reported by `gitea help`.
+   2. Add `github` to the comma-separated list in the setting `THEMES` in `app.ini`
+   3. Now users can select this theme in their settings under "account"
+   4. (optional) If you want to make this theme the default of your instance, set it in `DEFAULT_THEME` in `app.ini`
+
+## Changes to default Gitea theme
+
+- Aligned primary green, grey, red and blue colors with GitHub
+- Aligned `border-radius` with GitHub
+- Related theme by removing a lot of hover colors and dominant button background-colors
+- Aligned markup background to GitHub's value
+
