+# How to contribute
+
+We definitely welcome patches and contribution to this project!
+
+### Tips
+
+Commits must be formatted according to the [Conventional Commits Specification](https://www.conventionalcommits.org).
+
+Always try to include a test case! If it is not possible or not necessary,
+please explain why in the pull request description.
+
+### Releasing
+
+Commits that would precipitate a SemVer change, as described in the Conventional
+Commits Specification, will trigger [`release-please`](https://github.com/google-github-actions/release-please-action)
+to create a release candidate pull request. Once submitted, `release-please`
+will create a release.
+
+For tips on how to work with `release-please`, see its documentation.
+
+### Legal requirements
+
+In order to protect both you and ourselves, you will need to sign the
+[Contributor License Agreement](https://cla.developers.google.com/clas).
+
+You may have already signed it for other Google projects.

+# uuid
+The uuid package generates and inspects UUIDs based on
+[RFC 4122](https://datatracker.ietf.org/doc/html/rfc4122)
+and DCE 1.1: Authentication and Security Services. 
+
+This package is based on the github.com/pborman/uuid package (previously named
+code.google.com/p/go-uuid).  It differs from these earlier packages in that
+a UUID is a 16 byte array rather than a byte slice.  One loss due to this
+change is the ability to represent an invalid UUID (vs a NIL UUID).
