+# Requesting access to the Commit Queue and issue tracker
+
+If you need to request access for a user (or yourself) please ask a project owner to help. Googlers, email
+angle-team@google.com. External users, find a couple owners in the [OWNERS](../OWNERS) file and send a
+request via email.
+
+If you are an ANGLE owner and you want to grant a user access:
+
+ * For the Monorail issue tracker, add users via the ["People" administration console][MonorailPeople].
+ * For the ANGLE Commit Queue (CQ), grant try-job access via the [Chrome Infra Auth administration console][ChromeAdmin].
+ * The admin console also has a separate group for [CQ access][CQAccessAdmin].
