+    <p>Flatpak is installed by default on Fedora Workstation, Fedora Silverblue, and Fedora Kinoite. To get started, all you need to do is enable Flathub, which is the best way to get Flatpak apps. Flathub is pre-configured as a part of the <a href="https://docs.fedoraproject.org/en-US/workstation-working-group/third-party-repos/">Third-Party Repositories</a>. Alternatively, you can download and install the <a class="btn btn-default" href="https://dl.flathub.org/repo/flathub.flatpakrepo">Flathub repository file</a>.</p>

     <terminal-command>flatpak remote-add --if-not-exists flathub https://dl.flathub.org/repo/flathub.flatpakrepo</terminal-command>
