📘 Chapter 28 – Branching, Merging & Pull Requests

When working in teams, it’s best to use branches instead of editing main directly.

---

🔹 Branching

• A branch = separate version of the code
• Default branch → main

Create a Branch (GitHub Desktop)

• Branch → New Branch → name it (e.g., feature-login)
• Make changes → Commit → Push branch

---

🔹 Merging

• After finishing work, merge branch into main
• GitHub Desktop → Branch → Merge into main

---

🔹 Pull Requests (PRs)

• On GitHub Website → Go to repo
• Click Compare & Pull Request
• Review changes → Click Merge Pull Request
• Deletes the feature branch after merging (optional)
