Hello!
I was designing from scratch a Jekyll theme for my personal site and I thought it could be useful to others, so here I am publishing the basic files you need if you like it or if you want to contribute and make it better.
The current template has 3 main pages: a home page, an "about me" page, and a blog.
Set up your site at _config.yml and start by adding your content at about.md and index.md.
