+  This project is very active and we have a high turnover of pull requests.
+
+  Unfortunately, the number of incoming pull requests is higher than what our
+  reviewers can review and merge so there is a long backlog of pull requests
+  waiting for review. You can help here!
+
+  By reviewing another pull request, you will help raise the code quality of
+  that pull request and the final review will be faster. This way the general
+  pace of pull request reviews will go up and your wait time will go down.
+
+  When picking a pull request to review, try to choose one that hasn't yet
+  been reviewed.
+
+  Thanks for helping out!
