+# Purpose
+
+This repository exists to allow Googlers to collaborate and stage pull requests
+against the official Swift repository.
+
+# Contributing
+
+We strongly encourage contributors to contribute directly to upstream whenever
+possible; contributions will be rejected if the project owners feel they are
+more appropriate for a direct upstream contribution.
+
+If you would like to contribute to this repository, there are a few steps to
+follow:
+
+## Contributor License Agreement
+
+Contributions to this project must be accompanied by a Contributor License
+Agreement. You (or your employer) retain the copyright to your contribution,
+this simply gives us permission to use and redistribute your contributions as
+part of the project. Head over to https://cla.developers.google.com/ to see your
+current agreements on file or to sign a new one.
+
+You generally only need to submit a CLA once, so if you‘ve already submitted one
+(even if it was for a different project), you probably don’t need to do it
+again.
+
+## Code Reviews
+
+All submissions, including submissions by project members, require review. We
+use GitHub pull requests for this purpose. Consult GitHub Help for more
+information on using pull requests.
+
