 # Contribution guide
 
+/// note | Project-specific contribution guides
+
+This guide describes BeeWare's general contribution process. Some projects have their own
+contribution guides with additional requirements:
+
+* [Briefcase](https://briefcase.beeware.org/en/stable/how-to/contribute/)
+* [Toga](https://toga.beeware.org/en/stable/how-to/contribute/)
+* [Rubicon Objective-C](https://rubicon-objc.beeware.org/en/stable/how-to/contribute/)
+
+If the repository you want to contribute to is not on this list, follow the contribution
+guide for the most relevant project. For example, if you want to work on a Briefcase
+template repository, follow the Briefcase guide.
