Minor doc updates; split out changelog (#24)

* Escape underscore character

This seems to confuse most markdown parsers, so escape it.

* Consolidate dependency documentation

"general notes" were redundant with the listed dependencies in the
next section.

* Add more quickstart steps

I needed to add some steps locally—may or may not be correct for others!

* Split changelog into its own file
