Jekyll site for GitHub Pages.
First ensure Node.js is installed.
Then we need Grunt...
npm install -g grunt-cli
And [Yarn](https://yarnpkg.com/en/...
We also need Ruby. There's RubyInstall for Windows, and RVM for OS X. Make sure you install the Development Kit as well, it's separate installer usually (at least for Windows).
Now Bundler...
gem install bundler
Also ImageMagick. Make sure you install legacy utilities.
And the Gems from the project directory...
bundle install
Jeez!
Now you can install the Node modules. If Windows, make sure you run it from the Developer Command Prompt for VS2015.
npm install
And the Yarn modules
yarn install
Run grunt serve
from the command line to run the local development server
grunt deploy
will compile the site and push to the relevant GitHub repo.
