+Ansible Galaxy
+==============
+
+Kayobe uses a number of Ansible roles hosted on Ansible Galaxy. The role
+dependencies are tracked in ``requirements.yml``, and specify required
+versions. The process for changing a Galaxy role is as follows:
+
+#. If required, develop changes for the role. This may be done outside of
+   Kayobe, or by modifying the role in place during development. If upstream
+   changes to the role have already been made, this step can be skipped.
+#. Commit changes to the role, typically via a Github pull request.
+#. Request that a tagged release of the role be made, or make one if you have
+   the necessary privileges.
+#. Ensure that automatic imports are configured for the role using e.g. a
+   TravisCI webhook notification, or perform a manual import of the role on
+   Ansible Galaxy.
+#. Modify the version in ``requirements.yml`` to match the new release of the
+   role.
