General Workflow

• the develop branch is where ALL development starts from and merges to.
• the master branch ALWAYS matches production
• typical workflow would be branch a feature branch from develop, code and commit often. When code is readt for review & merge, open a Pull Request from the branch to develop.
• a typical deploy to production will take the develop branch and merge to master. The master branch will then be deployed to production machines.
• a hotfix is defined as a mission critical change that must be deployed to production with expediency.
  • the proper way to handle a hotfix is to branch from master and open a Pull Request from the branch to master
