+# Reviewing PRs
+
+Approving a PR means that the reviewer has deemed the PR ready to be merged.
+
+There are two steps to reviewing PRs.
+
+- Review the feature:
+
+  - Consider if the feature aligns with the [InfiniTime vision](InfiniTimeVision.md)
+  - Discuss alternative ideas or implementations
+
+- Review the code:
+
+  - Check the quality of the code and make sure it conforms to the [coding conventions](coding-convention.md)
+  - Consider the maintainability of the code
+  - Test the code with at least InfiniSim or a PineTime
+
+# Merging PRs
+
+Two approvals from core developers is usually required to merge a PR.
+Exceptions include urgent fixes
+and small maintenance PRs by core developers,
+that don't affect the apparent behaviour of the watch in any way.
+
+All but the simulator check must be passed before merging a PR.
+
+PRs are either rebase or squash merged,
+depending on whether the commits satisfy the following requirements:
+
+### Commits
+
+- Commits that fix mistakes from previous commits must be squashed before merging a PR.
+- The title and description of the commit must sufficiently explain the changes in the commit.
+
+If these requirements are not met,
+the PR must be squash merged,
+and the merger must write a satisfactory description.
+
+# Stale PRs
+
+Work-in-Progress PRs shall be marked as draft.
+
+Draft PRs with no activity by the author for 3 months may be closed as stale.
+
+PRs with changes requested, but no activity by the author for 3 months may be closed as stale.
