+## Project maintainers
 
 The Kata Containers project maintainers are the people accepting or
-rejecting any PR. They are listed in the `OWNERS` files. There can be one
-`OWNERS` file per directory.
+rejecting any PR. Although [anyone can review PRs](#reviews), only the
+acknowledgement (or "ack") from an Approver counts towards the approval of a PR.
 
-The `OWNERS` files split maintainership into 2 categories: reviewers and
-approvers. All approvers also belong to the reviewers list. There must be at
-least one approval from one member of each list for a PR to be merged.
+Approvers are listed in GitHub teams, one for each repository. The project
+uses the [Pull Approve](https://pullapprove.com) service meaning each
+repository contains a top level `.pullapprove.yml` configuration file. This
+file lists the GitHub team used for that repository's approvals.
 
-Since approvers are also reviewers, they technically can approve a PR without
-getting another reviewer's approval. However, it is their due diligence to
-rely on reviewers and should use their approval power only in very specific
-cases.
+Each repository can have custom review requirements but the minimum approval
+requirements are:
+
+- Two approvals from the approval team listed in the configuration file.
+
+- One [documentation team](https://github.com/orgs/kata-containers/teams/documentation/members)
+  approval if the PR modifies documentation.
+
+See the `.pullapprove.yml` configuration files for full details.
