@tylerjw Can you review the PR.

Thank you for your contribution. Unfortunately, this PR adds additional html syntax to the markdown README file which increases complexity of the file without bringing any major improvements. Therefore, I am closing this PR. Feel free to pick up any other work e.g. addressing one of the open first timer issues
