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
