+  For the sandboxed apps to work correctly, desktop integration portals need to be installed. 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.
