+# Processes
+
+This document outlines processes and procedures for some common tasks in the charts repository.
+
+## Adding chart maintainers
+
+Chart maintainers are defined within the chart itself.
+So the procedure for adding maintainers is to add them there.
+The pull request which does that should also update [CODEOWNERS](./github/CODEOWNERS) file to that the new maintainer is able to approve pull requests.
+One of the existing chart maintainers needs to approve the PR in addition one of the repository admins needs to approve it.
+They are then responsible for also granting the new maintainer write permissions to this repository.
