Making README/Doc Sections More SEO Friendly

[colto]

This is a pretty small deal, but I couldn't help but notice the section links on some of the docs were using Underscore VS Hyphen. It's a pretty minor change but should boost the searchablity of some of these sections.

For reference: https://www.seomechanic.com/seo-101-hyphens-underscores-_-urls/

This is awesome! I am going to make some issues on ALL of our other repos and link back to this one. Lots of awesome coming.

Thank you!!
