+Pull Request Merging Policy
+---------------------------
+
+Pull requests (PRs) are reviewed by the [merge team](https://github.com/orgs/contiki-os/people).
+Generally, PRs require two "+1" before they can be merged by someone on the merge team.
+The since Contiki 3.0, the merging policy is the following:
+* The PR receives **one "-1"** from a merge team member (along with specific feedback). The PR is closed. A "-1" must be accompanied with a clear explanation why the PR will not be considered for inclusion.
+* The PR receives **two "+1"** from merge team members. The PR is merged.
+* The PR was inactive for **two months**. A team member may either:
+  * Comment "Is there any interest for this PR? Is there any work pending on it? If not I will close it in **one month**." Back to initial state in case of activity, close otherwise.
+  * Comment "I approve this PR. If nobody disapproves within **one month**, I will merge it." Back to initial state in case of activity, merge otherwise.
+
+There is an exception to the rule.
+Code that requires esoteric expertise such as some applications, platforms or tools can be merged after a single "+1" from its domain expert.
