Starting from a chromium build as per http://dev.chromium.org/developers/how-tos/get-the-code Also looked at CEF https://code.google.com/p/chromiumembedded/, for later research.
Using @wercker for build and deployment pipelining. Installed https://atom.io/packages/wercker-status so I can keep an eye on it. Then I installed the command line tools following http://devcenter.wercker.com/articles/cli/installation.html
