+== *Core Concepts*:
+
+* A lightweight, branch-based workflow where `main` is always deployable
+* Feature branches are short-lived, created from `main` for every change
+* Pull Requests are the central collaboration mechanism — used for code review, discussion, and CI validation before merging
+* Merging to `main` triggers immediate deployment (continuous delivery)
+* Branch naming reflects the work: issue number or short descriptive slug
+
+Workflow steps::
+. Create a branch from `main` (named after the issue or feature)
+. Commit changes with descriptive messages
+. Open a Pull Request early for visibility and feedback
+. Discuss, review, and iterate until the PR is approved
+. Merge to `main` — `main` is always in a deployable state
+. Deploy immediately after merge
+
+Key Proponent:: Scott Chacon ("GitHub Flow", 2011)

+== *When to Use*:
+
+* Teams practicing continuous delivery or continuous deployment
+* Projects where `main` must always be production-ready
+* Issue-driven or ticket-driven development workflows
+* Agentic coding workflows where context brevity matters

+== *Kernkonzepte*:
+
+* Ein schlanker, branch-basierter Workflow, bei dem `main` immer auslieferbar ist
+* Feature-Branches sind kurzlebig und werden für jede Änderung aus `main` erstellt
+* Pull Requests sind der zentrale Kollaborationsmechanismus — für Code-Review, Diskussion und CI-Validierung vor dem Mergen
+* Das Mergen in `main` löst sofortige Auslieferung aus (Continuous Delivery)
+* Branch-Namen spiegeln die Arbeit wider: Issue-Nummer oder kurzer beschreibender Slug
+
+Workflow-Schritte::
+. Branch von `main` erstellen (benannt nach Issue oder Feature)
+. Änderungen mit aussagekräftigen Nachrichten committen
+. Pull Request frühzeitig öffnen für Transparenz und Feedback
+. Diskutieren, reviewen und iterieren bis der PR genehmigt ist
+. In `main` mergen — `main` ist immer auslieferbar
+. Sofort nach dem Merge deployen
+

+== *Wann zu verwenden*:
+
+* Teams, die Continuous Delivery oder Continuous Deployment praktizieren
+* Projekte, bei denen `main` stets produktionsbereit sein muss
+* Issue-getriebene oder Ticket-getriebene Entwicklungsworkflows
+* Agentische Coding-Workflows, bei denen Kontextkürze wichtig ist
