Hyde is a brazen two-column Jekyll theme that pairs a prominent sidebar with uncomplicated content. It's based on Poole, the Jekyll butler.
None of the code is actually mine. Here where it comes from https://github.com/poole/hyde
It's under MIT license.
I only did some changes and made it easier to setup.

1. Create a Github account, create a new repository and name it yourusername.github.io, go in to your repository>settings>pages, enable Github Pages using /(root).
2. Download the site template from here and unzip it. Upload the stuff inside it to your repository by simply dragging. It should look like mine.
3. Open config.yml and change title and baseurl. Base url needs to be your Github repository name. It should look like this https://username.github.io/ You should be able to visit your site by going into yourusername.github.io
