These are the steps to get started with github

Git

Install Git and configure name and email with the following commands:

git config --global user.name "User Name"
git config --global user.email "user@something.com"

SSH

Generate SSH key-pair with the following command:

ssh-keygen -t rsa

This tool will generate two files under directory ~/.ssh.  The default file names will be id_rsa and id_rsa.pub with public and private keys.

The public key is used to configure ssh in github by providing the content of id_rsa.pub (cat id_rsa.pub).

Check SSH Connection

Use the following command to confirm SSH is working correctly:

ssh -vT git@github.com
