+
+## Task 1
+
+### Importance of Signed Commits
+
+Commit signing is important as without it anyone can pretend to be another human by setting a name and email and create fake commits from another person.
+
+Commit signing prevents this by requiring private key to prove real authorship. If no private key isn't provided GitHub will mark it as Unverified.
+
+### Evidence of successful SSH key setup and signed commit
+
+![SSH Signing Keys](img/keys.png)
+
+The screenshot shows SSH key added to GitHub for authorization and signing.
+
+![GitHub Verified Commit Badge](img/verified_commit.png)
+
+The screenshot shows that commit is marked as **Verified** on GitHub.
+
+### Why is commit signing important in DevOps workflows?
+- Ensures commits come from trusted developers via digital signatures;
+- Tracks exactly who made code changes, aiding audits and debugging in CI/CD pipelines;
+- Protects the software supply chain by blocking unsigned commits, reducing risks of malicious code.
+
+## Task 2
+
+### PR Template
+
+![GitHub PR Existence](img/pr_template_existence.png)
+
+This screenshot shows that PR template exists in main branch of fork repository.
+
+![GitHub PR Template](img/pr_template.png)
+
+The screenshot shows that added PR template is used to auto-fill description.
+
+![GitHub PR](img/pr.png)
+
+This screenshot shows created PR with filled sections.
+
+### Why PR Template is beneficial
+
+Using PR templates improves collaboration because:
+- PRs follow a consistent structure, making reviewing process easier;
+- Remind developers to check changes against repository style and testing policies;
+- Provide ready-to-use sections to save time (no need to manually type them every time).
+
+### Challenges Encountered
+
+No challenges were encountered during PR template setup process.
