+# Extending Workflow
+
+Deis Workflow is an open source project which wouldn't be here without the amazing skill
+and enthusiasm of the community that has grown up around it. Several projects have blossomed
+which extend Workflow in various ways.
+
+These links are to community-contributed extensions of Deis Workflow. Deis makes no
+guarantees about the functionality, security, or code contained within. As with any software,
+use with caution in a production environment.
+
