Want to contribute? Great! First, read this page (including the small print at the end).

Before you contribute

Before we can use your code, you must sign the
Google Individual Contributor License Agreement
(CLA), which you can do online. The CLA is necessary mainly because you own the
copyright to your changes, even after your contribution becomes part of our
codebase, so we need your permission to use and distribute your code. We also
need to be sure of various other things—for instance that you'll tell us if you
know that your code infringes on other people's patents. You don't have to sign
the CLA until after you've submitted your code for review and a member has
approved it, but you must do it before we can put your code into our codebase.
Before you start working on a larger contribution, you should get in touch with
us first via email with your idea so that we can help out and possibly guide
you. Coordinating up front makes it much easier to avoid frustration later on.

Code reviews

All submissions, including submissions by project members, require review. We
use Gerrit for this purpose.

Setup

If you have not done so on this machine, you will need to set up a password for
Gerrit. Sign in with a Google account, visit
this link, and click the "Generate
Password" link in the top right. You will also need to prepare your checkout to
add Change-Ids
on commit. Run:

curl -Lo .git/hooks/commit-msg https://boringssl-review.googlesource.com/tools/hooks/commit-msg
chmod u+x .git/hooks/commit-msg

Uploading changes

To upload a change, push it to the special refs/for/master target:

git push origin HEAD:refs/for/master

The output will then give you a link to the change. Add agl@google.com and
davidben@google.com as reviewers.

Pushing a commit with the same Change-Id as an existing change will upload a new
version of it. (Use the git rebase or git commit --amend commands.)

For more detailed instructions, see the
Gerrit User Guide.

The small print

Contributions made by corporations are covered by a different agreement than
the one above, the
Software Grant and Corporate Contributor License Agreement.
