This is the part that confuses new users. Emby does not have a "Upload Theme" button. You must inject the CSS manually.

Step 1: Get the raw CSS. If using Ultrachromic, go to the ultrachromic.css file on GitHub and click "Raw". Copy everything.

Step 2: Navigate to Emby Server Dashboard. Go to http://your-server-ip:8096 > Login as Admin > Settings (Gear icon top right) > Advanced > General.
