9. The Rules • Anything on master is deployable. And will be. Like right now. • Work off of short-lived named branches • Open a pull request for help, feedback, and signoff • Once you merge, deploy immediately.
10. Do work on a branch Decide what's worth doing Automated tests Deploy to production Merge to master Manual tests auto-deploy feedback feedback feedback SCRUM or whatever

37. GitHub Flow
38. GitHub Flow is a version of Continuous Deployment
39. • Techniques such as automated testing, continuous integration and continuous deployment allow software to be developed to a high standard and easily packaged and deployed to test environments, resulting in the ability to rapidly, reliably and repeatedly push out enhancements and bug fixes to customers at low risk and with minimal manual overhead. Professor Wikipedia says:
40. …boring Continuous deployment is about developing and deploying in short, rapid increments.
41. Benefits for Developers: • A simple, easy-to-learn workflow • No release process • Frequent feedback • Low-risk, low-stress ships • Merge conflicts become trivial • Ownership, agency, quick wins, and responsibility

63. Hackable toolchain
64. CD needs to be automated • Builds on every commit • Results of signoff (feedback) • Deployment • Setup for manual tests • Communication
65. Implement on new branch Run build Communicate Build status Respond to build issues Create pull request (request feedback) Communicate ready for feedback Review Communicate review Respond to review signoff branch deploy Test in production Fix issues Re-deploy branch Merge branch integrate master Deploy master ! integrate master
