You'll probably want to hit enter for most/all of the default options. Especially the first one (where to save the key). When it's done, you'll probably see something like this:

This has created two files on your computer - id_rsa and id_rsa.pub. id_rsa is your '''private''' SSH key, and id_rsa.pub is the corresponding public key. You keep id_rsa to yourself, and you can give id_rsa.pub to admins to allow you to access a repository. You can also upload it to a remote server (like redbrick) and put it in a specific location to allow you passwordless logins, but you can google for how to do that.
