our staff to collaborate seamlessly with you, which increases our mutual
velocity and gives the community a bigger stake in our direction.
</p>

<p>
The Cloud Foundry team uses Gerrit, a code review tool that originated in the
Android Open Source Project. We also use GitHub as an official mirror, though
all pull requests are accepted via Gerrit.
