 This is fairly simple from a technical point of view! metalhead.club's local timeline is being watched using the
 Mastodon Streaming API over a Websocket. Every time a new post arrives, it is checked if it contains any music by
-checking included hashtags and URLs. A list of tags and URLs can be found in [the configuration](.env.EXAMPLE).
-Additionally, lins to YouTube are queried, if they are music or other videos using the YouTube API.

 If a post passes this check it is saved to a SQLite database.

+Copy `.env.EXAMPLE` to `.env` and add your `YOUTUBE_API_KEY` and `ODESLI_API_KEY`.
 To obtain one follow [YouTube's guide](https://developers.google.com/youtube/registering_an_application) to create an
 _API key_.
-If `YOUTUBE_API_KEY` is unset, all YouTube videos will be assumed to contain music links.
-If this is unwanted, set `YOUTUBE_DISABLE` to `true`).
+If `YOUTUBE_API_KEY` is unset, no playlist will be updated. Also, _all_ YouTube links will be treated as music videos,
+because the API is the only way to check if a YouTube link leads to music or something else.
+
+If `ODESLI_API_KEY` is unset, your rate limit to the song.link API will be lower.
+
+Add `MASTODON_ACCESS_TOKEN` as well, see [Creating our application

+`read:statuses` is the only required scope. An access token will be displayed in your settings. Use that!
+
+There are currently no plans to implement an actual authentication flow.

 Run `npm run build` and copy the output folder, usually `build` to `$APP_DIR` on your server.
