If you run GNOME, this will be handled automatically for you; in other cases, you will need to add something like the following to your <filename>configuration.nix</filename>: <programlisting> <xref linkend="opt-services.flatpak.extraPortals"/> = [ pkgs.xdg-desktop-portal-gtk ]; </programlisting> </para> <para> Then, you will need to add a repository, for example, <link xlink:href="https://github.com/flatpak/flatpak/wiki">Flathub</link>, either using the following commands: <programlisting> flatpak remote-add --if-not-exists flathub https://flathub.org/repo/flathub.flatpakrepo flatpak update </programlisting> or by opening the <link xlink:href="https://flathub.org/repo/flathub.flatpakrepo">repository file</link> in GNOME Software. </para> <para> Finally, you can search and install programs: <programlisting> flatpak search bustle flatpak install flathub org.freedesktop.Bustle flatpak run org.freedesktop.Bustle </programlisting> Again, GNOME Software offers graphical interface for these tasks. </para> </chapter>
