Branching strategy example

# Git Branching Modell (z.B. GitFlow Variante)

# Main/Master Branch (Manufacturing)
# Stable, represents the production code.
# Only merges from release branches or hotfixes.
git checkout main
git merge --no-ff release/v1.2.0
git tag -a v1.2.0 -m "Release Version 1.2.0"

# Develop branch (integration)
# Main development branch, integrates all features.
git checkout develop
git merge --no-ff feature/neues-dashboard

# Feature branches (for new features)
# Branched off develop, one branch per feature.
git checkout develop
git checkout -b feature/user-authentication
# ... development ...
git add .
git commit -m "Feature: user authentication implemented"
git push origin feature/user-authentication
# Create pull request to develop

# Release branches (preparation for releases)
# Branched off develop, for stabilization and bug fixes before release.
git checkout develop
git checkout -b release/v1.2.0
# ... bug fixes, tests, docs ...
# Merge to main and develop after approval

# Hotfix branches (for critical production defects)
# Branched off main, for quick fixes.
git checkout main
git checkout -b hotfix/kritischer-login-bug
# ... bug fix ...
# Merge to main and develop after approval
