+Deprecation policy
+---------------------------------------
+
+When a package is broken for more than one month, it can be deprecated
+and removed from the repository.
+
+The deprecation mechanism is the following:
+- Open an PR removing the deprecated package. **Don't mark it as WIP**
+  so team members are notified.
+- Add a deprecation tag to the PR.
+- Add a due date -- one month from the creation of the PR.
+- After the due date, if the package has not been fixed, it will be
+  effectively removed (the PR will be merged).
+
+ If you maintain another channel depending on Guix-Science, please
+ consider joining the ``companion`` team.
