For the impatient, here’s how to get a boilerplate Jekyll site up and running.
If you wish to install jekyll into the current directory, you can do so by
jekyll new . instead of a new directory name.
That’s nothing, though. The real magic happens when you start creating blog posts, using the front matter to control templates and layouts, and taking advantage of all the awesome configuration options Jekyll makes available.
If you’re running into problems, ensure you have all the requirements installed.
