+# Flatpak packaging
+
+This folder contains the files necessary to generate a Flatpak package for FreeDV. Flatpak
+is a container-based packaging scheme available on most common Linux distros that enables
+the generation of a single package that works on multiple systems with no modifications
+required.
+
+## Setting up a Flatpak build environment
+
+Execute the following command (Debian/Ubuntu):
+
+```
+$ git config --global protocol.file.allow always
+$ sudo apt install flatpak flatpak-builder gnome-software-plugin-flatpak
+$ flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo
+$ flatpak install flathub org.freedesktop.Platform//23.08 org.freedesktop.Sdk//23.08 
+```
+
+On other distros, the packages should be similar.
+
+## Generating a Flatpak package
+
+```
+$ flatpak-builder flatpak-build org.freedv.freedv.yml
+```
+
+## Installing and testing the generated package
+
+```
+$ flatpak-builder --user --install --force-clean flatpak-build org.freedv.freedv.yml
+$ flatpak run org.freedv.freedv
+```
+
+## Additional notes
+
+The Flatpak build container has no network access, so any new dependencies added to FreeDV will
+need to be downloaded and built as a separate module to ensure that the package can still be built.
