+## Branching in GitHub
+
+### What is a Branch?
+- A branch is a copy of the main codebase.
+- Allows working on features without affecting main branch.
+- Default branch is usually called main.
+
+### Creating and Using Branches
+- Branches are created from main.
+- Changes in branches remain isolated until merged.
+- Helps in experimentation and feature development.
+
+### Commits
+- A commit saves changes to the repository.
+- Each commit has:
+    - Unique ID
+    - Commit message
+- Commit messages explain why a change was made.
+
+### Pull Requests (PR)
+- A pull request proposes changes from one branch to another.
+- Shows differences (diffs) between branches.
+- Allows review and discussion before merging.
+
+### Merging a Pull Request
+- Combines branch changes into main.
+- Conflicts must be resolved before merge.
+- After merging, branches can be deleted safely.
+
+### Benefits of Pull Requests
+- Code review
+- Quality control
+- Clear change history
+- Team collaboration
