Improve documentation for website

[Mia-Y-Kelly]

I'd like to update the docs so that the descriptions of the functions are included on the README's. The links to the actual code are nice, but it would be more intuitive to have them also included on the website.

Not sure what you mean by adding the function descriptions to the readmes?

I may be incorrect, but it looks like the website pulls from Markdown files like this (for example) to show documentation. I would like to update them to include more verbose descriptions.
