+* __CUSTOM_DIRS__: whether to enable downloading videos into custom directories within the __DOWNLOAD_DIR__ (or __AUDIO_DOWNLOAD_DIR__). When enabled, a drop-down appears next to the Add button to specify the download directory. Defaults to `true`.
+* __CREATE_CUSTOM_DIRS__: whether to support automatically creating directories within the __DOWNLOAD_DIR__ (or __AUDIO_DOWNLOAD_DIR__) if they do not exist. When enabled, the download directory selector becomes supports free-text input, and the specified directory will be created recursively. Defaults to `true`.
 * __STATE_DIR__: path to where the queue persistence files will be saved. Defaults to `/downloads/.metube` 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`.

 I recommend installing and setting up [watchtower](https://github.com/containrrr/watchtower) for this purpose.
 
-## Build and run locally
+## Troubleshooting and submitting issues
+
+Before asking a question or submitting an issue for MeTube, please remember that MeTube is only a UI for [yt-dlp](https://github.com/yt-dlp/yt-dlp). Any issues you might be experiencing with authentication to video websites, postprocessing, permissions, other `YTDL_OPTIONS` configurations which seem not to work, or anything else that concerns the workings of the underlying yt-dlp library, need not be opened on the MeTube project. In order to debug and troubleshoot them, it's advised to try using the yt-dlp binary directly first, bypassing the UI, and once that is working, importing the options that worked for you into `YTDL_OPTIONS`.
+
+In order to test with the yt-dlp command directly, you can either download it and run it locally, or for a better simulation of its actual conditions, you can run it within the MeTube container itself. Assuming your MeTube container is called `metube`, run the following on your Docker host to get a shell inside the container:
+
+```bash
+docker exec -ti metube sh
+cd /downloads
+```
+
+Once there, you can use the yt-dlp command freely.
+
+## Building and running locally
 
 Make sure you have node.js and Python 3.8 installed.
