+## Getting Started with Jekyll
+
+We use the [jekyll](http://jekyllrb.com/) static site generator to build the
+site. If you don't have jekyll installed, do the following:
+
+1. Install a [Ruby](https://www.ruby-lang.org/en/). The version doesn't matter
+   too much, though you probably want to have a version of Ruby that is _at
+   least_ 2.0.0.
+1. Install jekyll. With your newly-installed Ruby powers, enter `gem install
+   jekyll`.
+   - Alteratively, you can `gem install bundler`, and then use `bundle install`
+     to install all of the dependencies in the [Gemfile](Gemfile). This is
+     likely much easier.
+
+You may find the [guide to
+jekyll](https://help.github.com/articles/setting-up-your-github-pages-site-locally-with-jekyll/)
+on the GitHub blog helpful.
+
+Once you have jekyll installed, you can build the site locally.
+
+- `jekyll build` will build the site. The generated site will be in
+  `(pwd)/_site`. You can view the site by pointing your browser to
+  `file:///(pwd)/_site/path/you/care/about`.
+- `jekyll serve` will build the site and start a local server (port 4000 by
+  default). You can view the site by pointing your browser to
+  `localhost:4000/path/you/care/about`. This option will also watch for file
+  changes and rebuild the site when you make edits.
