This repository is a Python cookiecutter; that is, a template with placeholders to be replaced when processed.
This particular template is for a git repository contianing everything required for a basic website using Github-Pages. It is possible to theme the website using one of several white listed Jekyll themes, but uses minima by default.
pip install cookiecutter
You can use this cookiecutter from the command line by calling
cookiecutter bill-richards/new-jekyll-site-cookiecutter
you will be presented with a series of prompts asking for the values to use when applying the template.
Ideally however, this cookicutter will be called by the Jekyll Site Template.
