Please note that this project is released with a Contributor Code of Conduct. By participating in this project you agree to abide by its terms.
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.
To contribute code or documentation, please submit a pull request.
A good way to familiarize yourself with the codebase and contribution process is to look for and tackle low-hanging fruit in the issue tracker.
If you would like to implement a new feature, please raise an issue before sending a pull request so the feature can be discussed before you start working on it.
Note: We appreciate your effort, and want to avoid a situation where a contribution requires extensive rework (by you or by us), sits in backlog for a long time, or cannot be accepted at all!
Please take a moment to check that an issue doesn't already exist documenting your bug report or improvement proposal. If it does, it never hurts to add a quick "+1" or "I have this problem too". This will help prioritize the most common problems and requests.
The project maintainers use LGTM (Looks Good To Me) in comments on the code review to indicate acceptance.
For a list of the maintainers, see the MAINTAINERS.md page.

We have tried to make it as easy as possible to make contributions. This applies to how we handle the legal aspects of contribution. We use the same approach - the Developer's Certificate of Origin 1.1 (DCO) - that the Linux® Kernel community uses to manage code contributions.
The rules are pretty simple: if you can certify the below (from developercertificate.org):
Developer Certificate of Origin
Version 1.1
Copyright (C) 2004, 2006 The Linux Foundation and its contributors.
660 York Street, Suite 102,
San Francisco, CA 94110 USA
Everyone is permitted to copy and distribute verbatim copies of this
license document, but changing it is not allowed.
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
it.
(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
maintained indefinitely and may be redistributed consistent with
this project or the open source license(s) involved.
then you just add a line to end of the git commit message:
Signed-off-by: John Doe <john.doe@example.com>
using your real name. Sorry, no pseudonyms or anonymous contributions.
Many Git UI tools have support for adding the Signed-off-by line to the end of your commit
message. This line can be automatically added by the git commit command by using the -s option.
