This theme has been tested to work without issue with gitea version 1.21.11
It has been reported that there are [issues](https://github.com/Jieiku/theme-dark-arc-gitea/issues/9) with gitea 1.22.0+ which at the time of this notice is currently Pre-Release status.
I plan to wait a little bit for changes to settle down before supporting 1.22.0+ so it is recommended to stick with 1.21.11 for the time being.
Create `/public/assets/css` below your $GITEA_CUSTOM path, MY custom path is `/var/lib/gitea/custom`, as seen in the [install screenshot](install.png).
Set ownership of your $GITEA_CUSTOM directory and files, I set ownership to git because gitea runs as user git, as seen in the [install screenshot](install.png).
The theme may automatically be active now, but if not click your avatar in top right, click settings, click appearance tab, select the theme and click update theme button.
As of [1.21.0](https://blog.gitea.com/release-of-1.21.0/#%EF%B8%8F-move-public-asset-files-to-the-proper-directory-25907) `/assets` now points to `custom/public/assets/*` instead of `custom/public/*`
