If you installed Lemmy with Docker, save your theme file to ./volumes/lemmy-ui/extra_themes. For native installation (without Docker), themes are loaded by lemmy-ui from ./extra_themes folder. A different path can be specified with LEMMY_UI_EXTRA_THEMES_FOLDER environment variable.

Copy the images from pictrs/image/ to the same directory of your instance

Use Stylus browser extention to customize your instance web page.

1. Copy the contents from {theme-name}.diff.css to Stylus.
