 ## For core developers
 
-Let's stick to the rule that no one (not even core developers) pushes directly to the repo. Every time one wants to make a change - even a silly one, it has to go through the Pull Request mechanism and at least one other core developer (one with push access to the repo) has to do a code review and agree with it before pulling it into `master`.

+### 14-day PR review window rule
+
+When there is an open PR with no blocking objections for at least 14 days, it can be merged without explicit approval of other team members.
+
+It's perfectly understandable that people don't have time to devote to AlexaPi to review stuff and if people with write access merge something even without a proper review, it will bring more good than harm to the project (keeps the development running, makes the project better as only people who have proved themselves have write access).
+
+An attempt to contact relevant team members has to be made (team mention for example). This rule is to account for people being busy, unavailable or unwilling rather than trying to sneak PRs through.
