Now that you've got the git bash (a.k.a git shell) installed, we need to setup a way to securely communicate with GitHub. This is an important step, but may be foreign to folks not familiar with running commands from a terminal.
SSH stands for Secure Shell - it's a protocol that allows you to remotely connect to servers and services (GitHub in this case). By enabling your machine to use SSH, you remove the need to supply a username and password everytime you connect to GitHub.
Fortunately, the folks at GitHub have already put together instructions for setting up SSH. To get up and running, start here
To successfully make it through the instructions, you will need to already have a GitHub account and have the git bash installed on your machine.
Hint: Notice that each set of instructions contains a link under the header that allows you to specify which operating system you are using.
Once you've run through these instructions, you'll be ready to move on to the next lesson.
