Today I created a new repository with the structure of my web.

www.github.com/migraine-io/mock-up

I learned to create a new repository from my terminal.
This is done as follows:

First you need to go to the folder you want to turn into a repository, then, you need to write the following:

git init
git add .
git commit -m "first commit"
git remote add origin git@github.com:migraine-io/mock-up.git
git push -u origin master

Simple right?

:)
