 # Building
+
+## Via flatpak (recommended)
+The recommended way to build is using flatpak, which will take care of all dependencies and avoid any problems that may come from different system configurations.
+
+First, install the required flatpak platform and SDK, if you dont have them already:
+```shell
+$ flatpak install org.gnome.{Platform,Sdk}//40 org.freedesktop.Sdk.Extension.rust-stable//20.08
+```
+
+To compile and install as a flatpak, run
+```shell
+$ flatpak-builder --install flatpak-build/ org.freedesktop.ryuukyu.Helvum.json
+```
+
+You can then run the app via
+```shell
+flatpak run org.freedesktop.ryuukyu.Helvum
+```
+
+## Manually
 For compilation, you will need:
 
 - An up-to-date rust toolchain
