Simple Git Workflow For Continuous Delivery

Workflow guidelines:

• master branch is always production-ready, deployable, 100% green test suite
• New development is done on feature branches, with frequent rebasing onto master
• Clean commit history by preferring to rebase instead of merge (git pull is configured to automatically rebase)

Workflow
