Notes

# Check GitHub pages required versions @ https://pages.github.com/versions/
# GitHub Pages info page:

#  - https://help.github.com/articles/using-jekyll-with-pages/

# Ruby is installed on Raspbian by default, but its only 1.9, we need at least 2.0
# Alas v2 isn't in the apt-get repo, but we can use the rvm to install it

# First we must add their GPG key
gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

# Now lets install Ruby 2.1.1, as thats what GitHub Pages use
\curl -sSL https://get.rvm.io | bash -s stable --ruby=2.1.1

# Install bundler
gem install bundler

# They say about creating a gemfile in the project folder, so something like:
mkdir project
cd project
vi Gemfile
# Then write:
source 'https://rubygems.org'
gem 'github-pages'

# then you could just install
bundle install
