+Work with others using branches and pull requests.
+
+## Goal
+
+Learn to collaborate on a shared repository using:
+- **Branches** - work independently without breaking main
+- **Pull Requests** - review and merge changes safely
+
+## The Workflow
+
+```
+1. Create branch    →    2. Make changes    →    3. Push branch
+                                                       ↓
+6. Delete branch    ←    5. Merge PR        ←    4. Create PR
+```
+
+This is how professional teams work together on code.
+
+---
+
+## Step 1: Clone the Repository
+
+Get the repository URL from your facilitator, then:
+
+```powershell
+git clone <repository-url>
+code <repository-name>
+```
+
+---
+
+## Step 2: Create a Branch
+
+Never work directly on `main`. Create your own branch:
+
+```powershell
+git switch -c <branch>
+```
+
+This creates a new branch and switches to it.
+
+---
+
+## Step 3: Make Changes
+
+1. Open `numbers.txt` in VS Code
+2. Move one number to its correct position
+3. Save the file (`Ctrl+S`)
+
+---
+
+## Step 4: Commit and Push
+
+```powershell
+git add .
+git commit -m "fix: move 7 to correct position"
+git push feature-2
+```
+
+Your branch is now on Azure DevOps.
+
+---
+
+## Step 5: Create a Pull Request
+
+1. Go to Azure DevOps in your browser
+2. Navigate to **Repos** → **Pull Requests**
+3. Click **New Pull Request**
+4. Set:
+   - **Source branch:** `feature/<your-name>`
+   - **Target branch:** `main`
+5. Add a title describing your change
+6. Click **Create**
+
+---
+
+## Step 6: Review and Merge
+
+1. Review the changes shown in the PR
+2. If everything looks good, click **Complete**
+3. Select **Complete merge**
+4. Your changes are now in `main`
+
+---
+
+## Step 7: Update Your Local Main
+
+After merging, update your local copy:
+
+```powershell
+git switch main
+git pull
+```
+
+---
+
+## Step 8: Repeat
+
+1. Create a new branch for your next change
+2. Make changes, commit, push
+3. Create another PR
+4. Continue until all numbers are sorted
+
+---
+
+## Quick Reference
+
+| Command | What It Does |
+|---------|--------------|
+| `git switch -c <name>` | Create and switch to new branch |
+| `git push -u origin <branch>` | Push branch to Azure DevOps |
+| `git switch main` | Switch to main branch |
+| `git pull` | Get latest changes from remote |
+
+---
+
+## Common Issues
+
+### "I accidentally committed to main"
+
+Switch to a new branch and push from there:
+```powershell
+git switch -c feature/<your-name>
+git push -u origin feature/<your-name>
+```
+
+### "My PR has conflicts"
+
+1. Update your branch with latest main:
+   ```powershell
+   git switch main
+   git pull
+   git switch feature/<your-name>
+   git merge main
