A practical Git workflow (branch → PR → merge)

Foundations Bootcamp

Lesson notes

Goal

Use Git the way teams actually work: small commits, feature branches, pull requests, reviews, and safe merges.

The Workflow (end-to-end)

main (stable)
  |
  +-- feature/my-change  (your work)

Steps:

  1. Sync with main
  2. Create a branch
  3. Commit small changes
  4. Push branch
  5. Open PR
  6. Review + fix
  7. Merge

Commands

Start clean

git status
git pull origin main

Create a feature branch

git checkout -b feature/add-login

Commit in small steps

git add .
git commit -m "Add login form UI"

Push and open PR

git push -u origin feature/add-login

What makes a good PR?

  • small and focused
  • clear title and description
  • includes tests or proof
  • easy to review

Merge strategies (what you will see)

  • squash merge: one clean commit
  • merge commit: preserves branch history
  • rebase + merge: linear history

Exercises

  1. Create a branch and make 2 commits.
  2. Push branch.
  3. Make a small fix commit.
  4. Merge using squash (if available) and pull main again.

Common mistakes

  • committing on main directly
  • huge PRs that are hard to review
  • not pulling latest main before starting

Next Step

Learn how to recover from mistakes: reset, revert, reflog.
