+## [4.0.6](https://github.com/eddyizm/tempo/releases/tag/v4.0.6) (2025-10-26)
+## Attention
+This release will not update previous installs as it is considered a new app, no longer `Tempo`, new icon, new app id, and new app name. Hoping it will not be a huge inconvenience but was necessary in order to publish to app stores like IzzyDroid and FDroid.  
+
+**Android Auto** 
+Support should be the same as before, however, I was not able to test any of the icons/visuals, so please let me know if there are any remnants of the tempo logo/icon as I believe I removed them all and replaced them successfully.

-This fork is my attempt to keep development moving forward and merge in PR's that have been sitting for a while in the main repo. Thankful to @CappielloAntonio for the amazing app and hopefully we can continue to build on top of it. I will only be releasing on github and if I am not able to merge back to the main repo, I plan to rename the app to be able to publish it to fdroid and possibly google play? We will see.

+
+## Prerequisites
+
+**Important Notice**: This app is a Subsonic-compatible client and does not provide any music content itself. To use this application, you must have:
+
+- An active Subsonic API server (or compatible service) already set up
+- Valid login credentials for your Subsonic server
+- Music content uploaded and organized on your server
+
+### Verified backends
+This app works with any service that implements the Subsonic API, including:
+- [LMS - Lightweight Music Server](https://github.com/epoupon/lms) -  *personal fave and my backend*
+- [Navidrome](https://www.navidrome.org/)
+- [Gonic](https://github.com/sentriz/gonic)
+
+
+
+
+## Getting Started
+
+### Installation
+1. Download the APK from the [Releases](https://github.com/eddyizm/tempus/releases) section
+2. Enable "Install from unknown sources" in your Android settings
+3. Install the application
+
+### First Launch
+1. Open the application
+2. You will be prompted to configure your server connection
+3. Grant necessary permissions for media playback and background operation
+
+## Server Configuration
+
+### Initial Setup
+**IN PROGRESS**
+1. Enter your server URL (e.g., `https://your-subsonic-server.com`)
+2. Provide your username and password
+3. Test the connection to ensure proper configuration
+
+### Advanced Settings
+**TODO**
+
+## Main Features
+
+### Library View
+
+**Multi-library**
+
+Tempus handles multi-library setups gracefully. They are displayed as Library folders. 
+
+However, if you want to limit or change libraries you could use a workaround, if your server supports it.
+
+You can create multiple users , one for each library, and save each of them in Tempus app.
+
+### Now Playing Screen
+
+On the main player control screen, tapping on the artwork will reveal a small collection of 4 buttons/icons. 
+<p align="left">
+    <img src="mockup/usage/player_icons.png" width=159>
+</p>
+
+*marked the icons with numbers for clarity* 
+
+1. Downloads the track (there is a notification if the android screen but not a pop toast currently )
+2. Adds track to playlist - pops up playlist dialog.
+3. Adds tracks to the queue via instant mix function
+    * TBD: what is the _instant mix function_?
+    * Uses [getSimilarSongs](https://opensubsonic.netlify.app/docs/endpoints/getsimilarsongs/) of OpenSubsonic API.
+      Which tracks to be mixed depends on the server implementation. For example, Navidrome gets 15 similar artists from LastFM, then 20 top songs from each.
+4. Saves play queue (if the feature is enabled in the settings) 
+    * if the setting is not enabled, it toggles a view of the lyrics if available (slides to the right) 
+
+
+## Navigation
+
+### Bottom Navigation Bar
+**IN PROGRESS**
+- **Home**: Recently played and server recommendations
+- **Library**: Your server's complete music collection
+- **Download**: Locally downloaded files from server 
+
+## Playback Controls
+
+### Streaming Controls
+**TODO**
+
+### Advanced Controls
+**TODO**
+
+## Favorites
+
+### Favorites (aka heart aka star) to albums and artists
+- Long pressing on an album gives you access to heart/unheart an album   
+
+<p align="center">
+    <img src="mockup/usage/fave_album.png" width=376>
+</p>
+
+- Long pressing on an artist cover gets you the same access to to heart/unheart an album   
+
+<p align="center">
+    <img src="mockup/usage/fave_artist.png" width=376>

+## Playlist Management
+
+### Server Playlists
+**TODO**
+
+### Creating Playlists
+**TODO**
+
+## Settings
+
+
+## Android Auto
+
+### Enabling on your head unit
+- You have to enable Android Auto developer options, which are different from actual Android dev options. Then you have to enable "Unknown sources" in Android Auto, otherwise the app won't appear as it isn't downloaded from Play Store. (screenshots needed)
+
+
+### Server Settings
+**IN PROGRESS**
+- Manage multiple server connections
+- Configure sync intervals
+- Set data usage limits for streaming
+
+### Audio Settings
+**IN PROGRESS**
+- Streaming quality settings
+- Offline caching preferences
+
+### Appearance
+**TODO**
+
+## Troubleshooting
+
+### Connection Issues
+
+**TODO**
+
+### Common Issues
+
+**TODO**
+
+### Support
+For additional help:
+- Question? Start a [Discussion](https://github.com/eddyizm/tempus/discussions)
+- Open an [issue](https://github.com/eddyizm/tempus/issues) if you don't find a discussion solving your issue. 
+- Consult your Subsonic server's documentation
