How to Review And Approve

• Go to the “Files changed” tab
• Here you will have the option to leave comments on different lines.
• Once the review is completed, find the “Review changes” button in the top right, select “Approve” (if you are really confident in the rule) or "Request changes" and click “Submit review”.
• Make sure to also review the proposed Call for Review period. In case of disagreement, the longer period wins.

Left a comment about two lines in the example that don't seem to be needed.

Do we need this line (and line 149)?
I don't think so, but just wanting to make sure.

The intention was to create a real case scenario, but I’m fine with removing them if we believe they could cloud the outcome.
