 * __DOWNLOAD_DIR__: path to where the downloads will be saved. Defaults to `/downloads` in the docker image, and `.` otherwise.
 * __AUDIO_DOWNLOAD_DIR__: path to where audio-only downloads will be saved, if you wish to separate them from the video downloads. Defaults to the value of `DOWNLOAD_DIR`.
+* __STATE_DIR__: path to where the queue-state-files will be saved. Defaults to `/state` in the docker image, and `.` otherwise.
 * __URL_PREFIX__: base path for the web server (for use when hosting behind a reverse proxy). Defaults to `/`.
 * __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`.
 * __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#L176). 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.
