   * __Note__: Using a RAM filesystem may prevent downloads from being resumed
 * __DELETE_FILE_ON_TRASHCAN__: if `true`, downloaded files are deleted on the server, when they are trashed from the "Completed" section of the UI. Defaults to `false`.
 * __URL_PREFIX__: base path for the web server (for use when hosting behind a reverse proxy). Defaults to `/`.
+* __PUBLIC_HOST_URL__: base URL for the download links shown in the UI for completed files. By default MeTube serves them under its own URL. If your download directory is accessible on another URL and you want the download links to be based there, use this variable to set it.
+* __PUBLIC_HOST_AUDIO_URL__: same as PUBLIC_HOST_URL but for audio downloads.
 * __OUTPUT_TEMPLATE__: the template for the filenames of the downloaded videos, formatted according to [this spec](https://github.com/yt-dlp/yt-dlp/blob/master/README.md#output-template). Defaults to `%(title)s.%(ext)s`.
 * __OUTPUT_TEMPLATE_CHAPTER__: the template for the filenames of the downloaded videos, when split into chapters via postprocessors. Defaults to `%(title)s - %(section_number)s %(section_title)s.%(ext)s`.
 * __YTDL_OPTIONS__: Additional options to pass to youtube-dl, in JSON format. [See available options here](https://github.com/yt-dlp/yt-dlp/blob/master/yt_dlp/YoutubeDL.py#L183). They roughly correspond to command-line options, though some do not have exact equivalents here, for example `--recode-video` has to be specified via `postprocessors`. Also note that dashes are replaced with underscores.
