+## Task 1 — SSH Commit Signing
+
+### Why signed commits are important
+
+Signed commits help verify that changes were made by a trusted author
+and that the commit history was not altered. This is important in
+DevOps workflows because it increases security, accountability,
+and trust in collaborative environments.
+
+### Proof of SSH signing
+
+The commit "docs: explain importance of signed commits" was created
+using SSH commit signing. On GitHub, this commit is marked with
+a green "Verified" badge, confirming the authenticity of the author.

+
+## Task 2 — Pull Request Template
+
+### PR template description
+
+A pull request template was added to the main branch of the repository.
+It includes sections for Goal, Changes, and Testing, as well as a
+checklist to ensure clear PR titles, updated documentation, and
+absence of sensitive data.
+
+### Proof of PR template usage
+
+A pull request from `feature/lab1` to `main` was created in my fork.
+The PR description was automatically populated using the pull request template.
+The checklist items were completed, demonstrating standardized PR workflow.
