Summary

Fixes #8 (closed) and #7 (closed) and #9 (closed)

Focus

Point the reviewer to the core of the code change. Where should they start reading? What should they focus on (e.g. security, performance, maintainability, user-friendliness, compliance with the specs, finding more corner cases, concrete questions)?

Test Environment

How to set up a test environment for manual testing?

Check List for the Author
