Contribution Guidelines
Security issues
If you are reporting a security issue, do not create an issue or file a pull request on GitHub. Instead, disclose the issue responsibly by sending an email to security@opencontainers.org (which is inhabited only by the maintainers of the various OCI projects).
Pull requests are always welcome
We are always thrilled to receive pull requests, and do our best to process them as fast as possible. Not sure if that typo is worth a pull request? Do it! We will appreciate it.
If your pull request is not accepted on the first try, don't be discouraged! If there's a problem with the implementation, hopefully you received feedback on what to improve.
We're trying very hard to keep the project lean and focused. We don't want it to do everything for everybody. This means that we might decide against incorporating a new feature.
Conventions
Fork the repo and make changes on your fork in a feature branch. For larger bugs and enhancements, consider filing a leader issue or mailing-list thread for discussion that is independent of the implementation. Small changes or changes that have been discussed on the project mailing list may be submitted without a leader issue.
If the project has a test suite, submit unit tests for your changes. Take a look at existing tests for inspiration. Run the full test suite on your branch before submitting a pull request.
Update the documentation when creating or modifying features. Test
your documentation changes for clarity, concision, and correctness, as
well as a clean documentation build. See docs/README.md for more
information on building the docs and how docs get released.
Write clean code. Universally formatted code promotes ease of writing, reading,
and maintenance. Always run gofmt -s -w file.go on each changed file before
committing your changes. Most editors have plugins that do this automatically.
Pull requests descriptions should be as clear as possible and include a reference to all the issues that they address.
Commit messages must start with a capitalized and short summary written in the imperative, followed by an optional, more detailed explanatory text which is separated from the summary by an empty line.
Code review comments may be added to your pull request. Discuss, then make the suggested modifications and push additional commits to your feature branch. Be sure to post a comment after pushing. The new commits will show up in the pull request automatically, but the reviewers will not be notified unless you comment.
Before the pull request is merged, make sure that you squash your commits into
logical units of work using git rebase -i and git push -f. After every
commit the test suite (if any) should be passing. Include documentation changes
in the same commit so that a revert would remove all traces of the feature or
fix.
Commits that fix or close an issue should include a reference like Closes #XXX
or Fixes #XXX, which will automatically close the issue when merged.
Sign your work
The sign-off is a simple line at the end of the explanation for the patch, which certifies that you wrote it or otherwise have the right to pass it on as an open-source patch. The rules are pretty simple: if you can certify the below (from developercertificate.org):
Developer Certificate of Origin

Developer's Certificate of Origin 1.1
By making a contribution to this project, I certify that:
(a) The contribution was created in whole or in part by me and I
have the right to submit it under the open source license
indicated in the file; or
(b) The contribution is based upon previous work that, to the best
of my knowledge, is covered under an appropriate open source
license and I have the right under that license to submit that
work with modifications, whether created in whole or in part
by me, under the same open source license (unless I am
permitted to submit under a different license), as indicated
in the file; or
(c) The contribution was provided directly to me by some other
person who certified (a), (b) or (c) and I have not modified

(d) I understand and agree that this project and the contribution
are public and that a record of the contribution (including all
personal information I submit with it, including my sign-off) is

then you just add a line to every git commit message:

using your real name (sorry, no pseudonyms or anonymous contributions.)
You can add the sign off when creating the git commit via git commit -s.
