GROUP 4 -Add example to Contributers.md file so people know how to contribute

## Add assignee instructions to CONTRIBUTING.md

**Problem:**
Multiple people might work on the same issue at once, causing duplicate work and confusion.

**Task:**
Add instructions about assigning yourself to issues before starting work.

**File Location:**
Navigate to `CONTRIBUTING.md`

**Instructions:**

1. Open `CONTRIBUTING.md`

2. Find the section "Making a Contribution" (around line 12)

3. Add a new subsection before the existing steps:
```markdown
### Before You Start
**Assign yourself to the issue** - Check if someone is already assigned. If the issue is unassigned, assign yourself before starting work.

### Steps
```

4. The existing numbered list should remain under the "Steps" header

**Result should look like:**
```markdown
