+**How to Squash (Step-by-Step Example):**
 
-```bash
-git rebase -i HEAD~N  # Replace N with the number of commits
-# Mark the first commit as 'pick' and subsequent commits as 'squash'
-git push --force-with-lease

+1. **Start Interactive Rebase:** Run the following command (replace `2` with the number of commits you want to combine):
+
+   ```bash
+   git rebase -i HEAD~2
+   ```
+
+2. **Edit the Rebase File:** An editor will open listing your recent commits. It will look like this:
+
+   ```text
+   pick a1b2c3d Message of the older commit
+   pick e4f5g6h Message of the newer commit
+   ```
+
+3. **Squash the Commits:** Change `pick` to `squash` (or `s`) for all commits except the first one:
+
+   ```text
+   pick a1b2c3d Message of the older commit
+   s e4f5g6h Message of the newer commit
+   ```
+
+4. **Save and Close:** Save the file and close the editor.
+
+5. **Finalize Message:** A new editor window will appear. Combine or edit the commit messages into a single, meaningful title (e.g., `WEB-123: Feature description`). Save and close.
+
+6. **Force Push:** Send the changes to your remote repository.
+   ```bash
+   git push origin branch-name --force-with-lease
+   ```
