 # Loop Client Release Notes
+This file tracks release notes for the loop client.
 
 ### Developers: 
+* When new features are added to the repo, a short description of the feature should be added under the "Next Release" heading.
+* This should be done in the same PR as the change so that our release notes stay in sync!
 
 ### Release Manager: 
+* All of the items under the "Next Release" heading should be included in the release notes.
+* As part of the PR that bumps the client version, cut everything below the 'Next Release' heading.
+* These notes can either be pasted in a temporary doc, or you can get them from the PR diff once it is merged.
+* The notes are just a guideline as to the changes that have been made since the last release, they can be updated.
+* Once the version bump PR is merged and tagged, add the release notes to the tag on GitHub.
