Open Source is Happening

#OurPhilosophy
==============
For anything to grow, you need three things:
Heat
====
Heat means work.
Upstream contributions, bug fixes, designs, docs--the rigorous work that drives the community.
Light
=====
Light means visibility.
For the projects, contributions, opportunities, challenges, and people that impact the community.
Love
====
Love means culture and support.
Why we care. How we work. Actions that grow the community.

================
Twitter has been built on open source since the beginning. Openness is part of our DNA. The projects you see here were born at Twitter, and patches are always welcome!
