    accTitle: Trunk-Based Development Workflow
    accDescr: Git history showing short-lived feature branches merging into main with release tags demonstrating trunk-based development

    commit id: "init"
    commit id: "setup CI"

    branch feature/auth
    checkout feature/auth
    commit id: "add login"
    commit id: "add tests"

    checkout main
    merge feature/auth id: "merge auth" tag: "v1.0"

    commit id: "update deps"

    branch feature/dashboard
    checkout feature/dashboard
    commit id: "add charts"
    commit id: "add filters"

    checkout main
    merge feature/dashboard id: "merge dash"

    commit id: "perf fixes" tag: "v1.1"

Tips

  • Use descriptive id: labels on commits
  • Add tag: for release versions
  • Branch names should match your actual convention (feature/, fix/, release/)
  • Show the ideal workflow — this is prescriptive, not descriptive
  • Use type: HIGHLIGHT on important merge commits
  • Keep to 10–15 commits maximum for readability
