+## Build
+
+- for Linux desktop builds: `sudo apt install libmpv-dev mpv`
+- [install rust](https://www.rust-lang.org/tools/install) (for some dependencies)
+- [install flutter](https://docs.flutter.dev/get-started/install)
+- required for android builds: [install android-studio](https://developer.android.com/studio)
+- required for macos builds: [install xcode](https://developer.apple.com/xcode/)
+- as a good IDE for all builds: [install vcode](https://code.visualstudio.com/)
+
 ## Testing
 
 Test mocks are generated with [Mockito](https://github.com/dart-lang/mockito). You need to run the `build_runner` command in order to re-generate mocks, in case you changed the signatures of service methods.
