-# rawtherapee
+This is the module definition for Rawtherapee. It's pretty simple, so there
+shouldn't need to be many changes. See https://src.fedoraproject.org/rpms/rawtherapee
+for the RPMs.
+
+There are two streams: devel and stable. The `stable` stream tracks upstream
+releases closely, after some basic testing. We may also include critical
+security fixes, but again in general we follow an upstream-first model.
+
+The `devel` stream is less cautious. We may include release candidates,
+nightly builds, or other experimental / in-development builds.
