1# How to contribute
2
3We definitely welcome patches and contribution to this project!
4
5### Tips
6
7Commits must be formatted according to the [Conventional Commits Specification](https://www.conventionalcommits.org).
8
9Always try to include a test case! If it is not possible or not necessary,
10please explain why in the pull request description.
11
12### Releasing
13
14Commits that would precipitate a SemVer change, as described in the Conventional
15Commits Specification, will trigger [`release-please`](https://github.com/google-github-actions/release-please-action)
16to create a release candidate pull request. Once submitted, `release-please`
17will create a release.
18
19For tips on how to work with `release-please`, see its documentation.
20
21### Legal requirements
22
23In order to protect both you and ourselves, you will need to sign the
24[Contributor License Agreement](https://cla.developers.google.com/clas).
25
26You may have already signed it for other Google projects.

1# uuid
2The uuid package generates and inspects UUIDs based on
3[RFC 4122](https://datatracker.ietf.org/doc/html/rfc4122)
4and DCE 1.1: Authentication and Security Services.
5
6This package is based on the github.com/pborman/uuid package (previously named
7code.google.com/p/go-uuid). It differs from these earlier packages in that
8a UUID is a 16 byte array rather than a byte slice. One loss due to this
9change is the ability to represent an invalid UUID (vs a NIL UUID).
