 ## Hacking
 
+### Building
+
 Musicus uses the [Meson build system](https://mesonbuild.com/). You can build
 it using the following commands:

 Afterwards the resulting binary executable is under
 `build/target/debug/musicus`.
 
+### Flatpak
+
+There is a Flatpak manifest file called `de.johrpan.musicus.json`. To build a
+Flatpak you need the the latest Gnome SDK and the Freedesktop SDK with the Rust
+extension. You can install those using the following commands:
+
+```
+$ flatpak remote-add --user --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
+$ flatpak remote-add --user --if-not-exists gnome-nightly https://nightly.gnome.org/gnome-nightly.flatpakrepo
+$ flatpak install --user gnome-nightly org.gnome.Sdk org.gnome.Platform
+$ flatpak install --user flathub org.freedesktop.Sdk.Extension.rust-stable//19.08
+```
+
+Afterwards, the following commands will build, install and run the application:
+
+```
+$ rm -rf flatpak
+$ flatpak-builder --user --install flatpak de.johrpan.musicus.json
+$ flatpak run de.johrpan.musicus
+```
+
+### Special requirements
+
 This program uses [Diesel](https://diesel.rs) as its ORM. After installing
 the Diesel command line utility, you will be able to create a new schema
 migration using the following command:
