Theme is based on Slim Pickins.
Thanks to ShmooCon for some navigation and content help.
If you haven't run this previously, start with bundle install to install all of the gems necessary for the site.
To run the site locally, run bundle exec jekyll serve or rake watch on the command line. The address will be listed as Server address in the output when this runs correctly.
You can create a new page in _pages, which will generate the page at the root of the site. The top of your page (md or html) should look like:
---
layout: page
title: "My Page Title"
---
After that you can put your content in either html or md form, depending on your file extension. filename.md will become filename.html
If you want the page to be linked, you should update _data/nav.yml with the proper location in the navigation.
