15. Environment Types
 Local (Workstation) – the current code
 CI (Continuous Integration) – feature branches
 QA (Quality Assurance, Quality Control) – a ‘develop’ branch
 UAT (User Acceptance Testing) – the ‘master’ branch
 Stage (Staging) – artefacts from UAT
 Production – artifacts from UAT
