 # CONFIGURATION
 
 You can configure yt-dlp by placing any supported command line option in a configuration file. The configuration is loaded from the following locations:

 #### youtube
 * `lang`: Prefer translated metadata (`title`, `description` etc) of this language code (case-sensitive). By default, the video primary language metadata is preferred, with a fallback to `en` translated. See [youtube.py](https://github.com/yt-dlp/yt-dlp/blob/c26f9b991a0681fd3ea548d535919cec1fbbd430/yt_dlp/extractor/youtube.py#L381-L390) for list of supported content language codes
 * `skip`: One or more of `hls`, `dash` or `translated_subs` to skip extraction of the m3u8 manifests, dash manifests and [auto-translated subtitles](https://github.com/yt-dlp/yt-dlp/issues/4090#issuecomment-1158102032) respectively
-* `player_client`: Clients to extract video data from. The currently available clients are `web`, `web_safari`, `web_embedded`, `web_music`, `web_creator`, `mweb`, `ios`, `android`, `android_vr`, `tv` and `tv_embedded`. By default, `tv,ios,web` is used, or `tv,web` is used when authenticating with cookies. The `web_music` client is added for `music.youtube.com` URLs when logged-in cookies are used. The `tv_embedded` and `web_creator` clients are added for age-restricted videos if account age-verification is required. Some clients, such as `web` and `web_music`, require a `po_token` for their formats to be downloadable. Some clients, such as `web_creator`, will only work with authentication. Not all clients support authentication via cookies. You can use `default` for the default clients, or you can use `all` for all clients (not recommended). You can prefix a client with `-` to exclude it, e.g. `youtube:player_client=default,-ios`
-* `player_skip`: Skip some network requests that are generally needed for robust extraction. One or more of `configs` (skip client configs), `webpage` (skip initial webpage), `js` (skip js player). While these options can help reduce the number of requests needed or avoid some rate-limiting, they could cause some issues. See [#860](https://github.com/yt-dlp/yt-dlp/pull/860) for more details

One or more of `configs` (skip client configs), `webpage` (skip initial webpage), `js` (skip js player), `initial_data` (skip initial data/next ep request). While these options can help reduce the number of requests needed or avoid some rate-limiting, they could cause issues such as missing formats or metadata.

 * `player_params`: YouTube player parameters to use for player requests. Will overwrite any default ones set by yt-dlp.
+* `player_js_variant`: The player javascript variant to use for signature and nsig deciphering. The known variants are: `main`, `tce`, `tv`, `tv_es6`, `phone`, `tablet`. Only `main` is recommended as a possible workaround; the others are for debugging purposes. The default is to use what is prescribed by the site, and can be selected with `actual`
 * `comment_sort`: `top` or `new` (default) - choose comment sorting mode (on YouTube's side)
 * `max_comments`: Limit the amount of comments to gather. Comma-separated list of integers representing `max-comments,max-parents,max-replies,max-replies-per-thread`. Default is `all,all,all,all`
     * E.g. `all,all,1000,10` will get a maximum of 1000 replies total, with up to 10 replies per thread. `1000,all,100` will get a maximum of 1000 comments, with a maximum of 100 replies total

+# YoutubeIE PO Token Provider Framework
+
+As part of the YouTube extractor, we have a framework for providing PO Tokens programmatically. This can be used by plugins.
+
+Refer to the [PO Token Guide](https://github.com/yt-dlp/yt-dlp/wiki/PO-Token-Guide) for more information on PO Tokens.
+
+> [!TIP]
+> If publishing a PO Token Provider plugin to GitHub, add the [yt-dlp-pot-provider](https://github.com/topics/yt-dlp-pot-provider) topic to your repository to help users find it.
+
+
+## Public APIs
+
+- `yt_dlp.extractor.youtube.pot.cache`
+- `yt_dlp.extractor.youtube.pot.provider`
+- `yt_dlp.extractor.youtube.pot.utils`
+
+Everything else is internal-only and no guarantees are made about the API stability.
+
+> [!WARNING]
+> We will try our best to maintain stability with the public APIs.
+> However, due to the nature of extractors and YouTube, we may need to remove or change APIs in the future.
+> If you are using these APIs outside yt-dlp plugins, please account for this by importing them safely.

+
+## Logging Guidelines
+
+- Use the `self.logger` object to log messages.
+- When making HTTP requests or any other expensive operation, use `self.logger.info` to log a message to standard non-verbose output.
+  - This lets users know what is happening when a time-expensive operation is taking place.
+  - It is recommended to include the PO Token context and internal client name in the message if possible.
+  - For example, `self.logger.info(f'Requesting {request.context.value} PO Token for {request.internal_client_name} client from external provider')`.
+- Use `self.logger.debug` to log a message to the verbose output (`--verbose`).
+  - For debugging information visible to users posting verbose logs.
+  - Try to not log too much, prefer using trace logging for detailed debug messages.
+- Use `self.logger.trace` to log a message to the PO Token debug output (`--extractor-args "youtube:pot_trace=true"`). 
+  - Log as much as you like here as needed for debugging your provider.
+- Avoid logging PO Tokens or any sensitive information to debug or info output.
+
+## Debugging
+
+- Use `-v --extractor-args "youtube:pot_trace=true"` to enable PO Token debug output.
+
+## Caching
+
+> [!WARNING]
+> The following describes more advance features that most users/developers will not need to use.
+
+> [!IMPORTANT]
+> yt-dlp currently has a built-in LRU Memory Cache Provider and a cache spec provider for WebPO Tokens. 
+> You should only need to implement cache providers if you want an external cache, or a cache spec if you are handling non-WebPO Tokens.
+
+### Cache Providers
+
+`yt_dlp.extractor.youtube.pot.cache`
