Git branching strategies organize work and enable parallel development. Feature branching creates separate branches for each feature or bug fix. Main branch remains stable and deployable at all times. Git Flow uses develop branch for integration with feature branches. Release branches prepare for production deployment. Hotfix branches address production issues from main. GitHub Flow simplifies to feature branches and main only. Trunk-based development encourages small, to main. Branch naming conventions like feature/xyz or bugfix/xyz improve organization. Pull request templates standardize review information. Branch protection rules require reviews and status checks. Delete branches after merging to maintain cleanliness. Squash merging combines feature commits into one. Rebase merging maintains linear history. Regular sync with upstream branch prevents large merge conflicts. Short-lived branches reduce merge complexity. Feature flags enable testing incomplete features in production. Semantic branch names connect to issue tracking. Code owners automatically assign relevant reviewers. Team-wide branching strategy documentation is essential.
