 Under normal circumstances, Home Assistant automatically discovers your running Music Assistant Server. If there is something special about the Home Assistant or MA setup (for example, the MA server is running as a remote Docker container) or discovery is not working, you can manually specify the URL to your Music Assistant server. If the Music Assistant Server is not installed, then follow these [installation instructions](https://music-assistant.io/installation/).

+### Media player entities

+The Music Assistant integration creates media player entities for all players and groups available in MA, including those imported from Home Assistant. This is needed to provide the full functionality Music Assistant has to offer. This full functionality includes transfer of the playing queue of music from one player to another, automatic pausing of playback during announcements and richer options for selecting the media for playback. These entities will display media information, playback progress, and playback controls.

+## Known limitations
+
+The `get_queue` action only returns the current and next item in the queue. This is because a large amount of data is returned and if this was done for potentially thousands of tracks this could have an adverse impact on HA performance or stability. 
+
+The data returned by the `get_queue` action will be partially limited if the item is not in the library (e.g. an item was selected for playback directly from Spotify). Metadata such as favorite status, explicit status, last played, played count and disc art URL are only available for items which are in the MA library. 
+
+Radio mode is only available with certain music providers and an error will be shown if attempting to enable radio mode on an item that isn't linked to one of those providers. Review the Music Assistant documentation to identify which providers support this functionality.
+
 ## Notes
 
 - Any Home Assistant players added to Music Assistant will appear duplicated as the MA version of the player is created. The original HA player can be hidden if desired.
 
+## Troubleshooting
+
+### Can’t find the MA actions
+
+#### Symptom: No Music Assistant actions are shown in the editor
+
+When trying to set up a script or automation via the GUI no MA actions can be found
+
+##### Description

+
+##### Resolution
+
+Go to the [Configuration section](https://www.home-assistant.io/integrations/music_assistant/#configuration) and install the integration.
