Fedora's repository for package maintenance.
Welcome, if you're looking to download software to run, look at https://getfedora.org/, or a Fedora Mirror. You can also find source RPMs for Fedora-packaged software there. The source code for building those packages is found here.
If you are looking for RPM spec files, module and container definitions, Fedora-specific patches, tests, and so on, you're in the right place. You can browse packages and packagers — and you can fork, improve, and submit pull requests.
Note that package issues are still tracked in Bugzilla, not with Pagure's issue feature.
