 In DevOps, many people work on the same code. Signed commits help us know exactly who made each change. It stops attackers or mistakes from unknown people, and is required for security in many companies.

+## Task 2: PR Template & Checklist
+

+
+### 2. Screenshot of PR Template Auto-fill
+
+![PR template autofill screenshot](screenshots/pr_template_autofill.png)
+
+### 3. How PR Templates Help
+
+PR templates help teams to remember all important information for every pull request. It makes review easier and reduces mistakes.
+
+### 4. Challenges
+
+At first, the template did not appear because I created PR before adding the file to main. I learned the template must be in main before PR.
