+== Third-Party Tools and Extensions
+
+Here is a collection of tools and extensions that relate to Home
+Manager. Note, these are maintained outside the regular Home Manager
+flow so quality and support may vary wildly. If you encounter problems
+then please raise them in the corresponding project, not as issues in
+the Home Manager tracker.
+
+If you have made something interesting related to Home Manager then
+you are encouraged to create a PR that expands this chapter.
