To setup the environment.

Some of the posts rely on graphviz, so install it.

I've used rbenv in the past, though the most recent time I didn't bother.

• install rbenv
• install rbenv-build
• build Ruby using rbenv install

As an alternative, on Debian:

• sudo apt-get install ruby-full

See the jekyll directions

• gem install jekyll bundler

Go to babysteps directory and run bundle update --bundler
