+# ARM notification group
+
+**Github Label:** [O-ARM]
+
+[O-ARM]: https://github.com/rust-lang/rust/labels/O-ARM
+
+This list will be used to ask for help both in diagnosing and testing
+ARM-related issues as well as suggestions on how to resolve
+interesting questions regarding our ARM support.
+
+The group also has an associated Zulip stream (`#t-compiler/arm`)
+where people can go to pose questions and discuss ARM-specific
+topics.
+
+So, if you are interested in participating, please sign up for the
+ARM group! To do so, you open a PR against the [rust-lang/team]
+repository. Just [follow this example][eg], but change the username to
+your own!
