Documentation Request Checklist

• I have read and agree to Mocha's Code of Conduct and Contributing Guidelines
• I have searched for related issues and issues with the faq label, but none matched my issue.
• I want to provide a PR to resolve this

Overview

I was struggling to host the API docs after reading docs/readme.md. I have learned that I need to run docs:api, but I'd like that to be included in the readme for other developers

Additional Info

I have a PR ready :)
