 We love improvements to our tools! EDGI has general [guidelines for contributing][edgi-contributing] and a [code of conduct][edgi-conduct] for all of our organizational repos.
 
-## Here are some notes specific to this project:
-
-* We have configured this project on CircleCI to [only run on pull
-  requests and `main` branch][pr-config]– so if you PR from a fork, the Circle CI build will fail! Please PR from a branch instead (you will need permissions).
-* We have further configured CircleCI to **NOT** delete videos from Zoom on runs related to pull requests. (As mentioned in README, videos are normally deleted after upload.)
