== Summary ==
Enabling third-party repositories will now create a Flathub remote
that is a filtered view of Flathub.


== Detailed Description ==
'''''Note that this proposal is about user experience, procedures, and
technology - the high-level concept has already been discussed and
approved by the Fedora Council and FESCO.'''''

Enabling third-party repositories will now create a Flathub remote
that is a filtered view of Flathub. This means that applications on
Flathub that have been explicitly approved (by a new process proposed
here) will be available in GNOME Software and on the
<code>flatpak</code> command line. If the user follows following the
instructions on https://flatpak.org/setup/Fedora/, then the filter is
removed, and the user gets a full view of Flathub.

Roughly speaking, the criteria for including software is a) will not
cause legal or other problems for Fedora to point to b) does not
overlap Fedora Flatpaks or software in Fedora that could easily be
made into a Flatpak c) works reasonably well. For Fedora 35, We expect
to include all software from the top 50 most popular applications on
Flathub that meet these criteria plus selected other software of
interest to the Fedora target audience - Fedora community members are
welcome to propose additions.
