DISABLE_THEME="false"

## FAQ

  # If you update the DOMAIN variable after the script has been run,
  # you must disable the whole theme with the DISABLE_THEME="true" env first and re-run it again after with "false".

  # Your domain can be your custom domain or a github pages (user.github.io) etc. Don't add the whole URL with scheme, you only need to add the domain.
    # If you are using your own github.io domain you must prepend /theme.park on all @imports/URLs in the css files. e.g. @import url(/theme.park/css/addons/unraid/login-page/retro-terminal/retro-terminal-base.css);

  # If your custom domain uses a subfolder you must escape the forward slash. (custom.com\/subfolder)

  # If you are on an Unraid version older than 6.10 you need to update the LOGIN_PAGE variable to "/usr/local/emhttp/login.php"
