Watch/read these links in order and practice in your personal git repository at the same time. You should memorize the basic git commands and their usage.

ssh-keygen. Press ENTER 3 times to accept default options.
$ ssh-keygen -t rsa -C "<your-email>"
Generating public/private rsa key pair.
Enter file in which to save the key (/Users/manthony/.ssh/id_rsa):
Created directory '/Users/manthony/.ssh'.
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /Users/manthony/.ssh/id_rsa.
Your public key has been saved in /Users/manthony/.ssh/id_rsa.pub.
The key fingerprint is:

+-----------------+- Start the ssh-agent and load your keys:
- Open a terminal window and enter the following command to see if the agent is running:
$ ps -e | grep [s]sh-agent
9060 ?? 0:00.28 /usr/bin/ssh-agent -l- If the agent isn't running, start it manually with the following command:
$ ssh-agent /bin/bash- Load your new identity into the ssh-agent management program using the ssh-add command.
$ ssh-add ~/.ssh/id_rsa
Enter passphrase for /Users/manthony/.ssh/id_rsa:
Identity added: /Users/manthony/.ssh/id_rsa (/Users/manthony/.ssh/id_rsa)- Use the ssh-add command to list the keys that the agent is managing.
$ ssh-add -l
2048 7a:9c:b2:9c:8e:4e:f4:af:de:70:77:b9:52:fd:44:97 /Users/manthony/.ssh/id_rsa (RSA)- Install the public key on your Github account
- Open a browser and log into Github.
- Choose avatar > Your profile from the application menu.
- The system displays the Personal settings page.
- Click SSH keys.
- The SSH Keys page displays. It shows a list of any existing keys. Then, below that, a dialog for labeling and entering a new key.
- Back in your terminal window, copy the contents of your public key file.
- For example, in Linux you can cat the contents.
$ cat ~/.ssh/id_rsa.pub- Back in your browser, enter a Label for your new key, for example, Default public key.
- Paste the copied public key into the SSH Key field:
- Press Add key.
- The system adds the key to your account.
Pro Git is the best book on Git. It is written by one of the cofounders of GitHub. Read ch 2 and 3 to get started. I recommend reading the whole book if you are interested.
