+# Maintainers
+This page describes the current module, library, and extension maintainers of Ruby.
+
+## Module Maintainers
+A module maintainer is responsible for a certain part of Ruby.
+
+* The maintainer fixes bugs of the part. Particularly, they should fix
+  security vulnerabilities as soon as possible.
+* They handle issues related the module on the Redmine or ML.
+* They may be discharged by the 3 months rule [ruby-core:25764].
+* They have commit right to Ruby's repository to modify their part in the
+  repository.
+* They have "developer" role on the Redmine to modify issues.
+* They have authority to decide the feature of their part. But they should
+  always respect discussions on ruby-core/ruby-dev.
+
+A submaintainer of a module is like a maintainer. But the submaintainer does
+not have authority to change/add a feature on his/her part. They need
+consensus on ruby-core/ruby-dev before changing/adding. Some of submaintainers
+have commit right, others don't.
