Yes we started doing this around 6 months ago. We started using [Github PR templates](https://docs.github.com/en/communities/using-templates-to-en...) to prompt for instructions on how to run and test the PR. We are seeing following benefits :

- We are finding deficiencies in our testing/development methods. The more people have to test/run code the more we are able to find bottlenecks and eliminate them.

- Knowledge sharing. We found that team members had knowledge/tricks in their heads which are being shared more.

- The overall reliability of our systems(measured via SLOs) has greatly increased.
