+## Project structure
+
+The top level directories contain the main Musicus packages, of which some
+depend on other ones. All packages are written in [Dart](https://dart.dev).
+
+### `database`
+
+A Database of classical music. This package will be used by all standalone
+Musicus applications for storing classical music metadata.
+
+### `mobile`
+
+The Musicus mobile app. It is being developed using
+[Flutter toolkit](https://flutter.dev) and only runs on Android for now.
+
+### `player`
+
+The simplest possible audio player plugin. This is used by the mobile app for
+playback.
+
 ## Hacking
 
+Picking up Dart as a programming language and Flutter as an UI toolkit should
+be relatively straight forward. You can visit
+[this page](https://flutter.dev/docs/get-started/install) to get started with
+Flutter. After cloning the Musicus repository, it works best to work at its
+subcomponents one at a time. I recommend
+[VS Code](https://flutter.dev/docs/get-started/editor?tab=vscode) for editing.
+Please contact me via e-mail (see my profile), if you have any questions or
+need help. I'm also open to ideas for the future of Musicus! Please use the
+issue tracker for them.
