+F5 requires all external contributors to agree to the terms of the F5 CLA (available [here](https://github.com/f5/.github/blob/main/CLA/cla-markdown.md)) before any of their changes can be incorporated into an F5 Open Source repository.
+
+If you have not yet agreed to the F5 CLA terms and submit a PR to this repository, a bot will prompt you to view and agree to the F5 CLA. You will have to agree to the F5 CLA terms through a comment in the PR before any of your changes can be merged. Your agreement signature will be safely stored by F5 and no longer be required in future PRs.
