+Pagure Dist Git Interactions by Fedora Packagers
+================================================
+
+Fedora Packagers are the group of Fedora contributors that use pagure-dist git
+to manage specfiles and patches on packages.
+
+Fedora Packagers use pagure dist-git to store specfiles and patches for all the
+packages in the Fedora distribution.
+
+There are two main workflows that a packager may utilise with interacting with dist-git.
+The first is the traditional way by committing changes directly to the dist-git repo.
+The second is using the PR-based workflow that pagure provides.
+
+The Source tarballs are not stored in dist-git, but handled seperately by the lookaside
+cache system. When preparing sources, a packager will use the `fedpkg upload` or 
+`fedpkg new-sources` commands to upload a tarball to the lookaside cache and update 
+the sources file on their local checkout. This file is then updated using one of the two
+workflows (git push or PR)
