-
 1. Create an "SSH Key"
+
    - Head to your terminal and enter the following command (using the email address you sign into GitHub with)
 
      ```bash
      ssh-keygen -t rsa -b 4096 -C "youremail@example.com"
      ```
 
-- This will prompt you for a file location. Just accept the default
-
-    ```bash
-    Enter file in which to save the key (/Users/yourname/.ssh/id_rsa):
-    ```
-
-- It will then prompt you for a password to lock down this file. Enter one you can remember.
-
-    > Note that you are free to leave this blank if you want to avoid typing passwords every time you use git. It's fine, although not terribly secure if someone gets ahold of your laptop
-
-    ```bash
-    Enter passphrase (empty for no passphrase):
-    ```
-
-- Once complete, it'll give you output that looks similar to this:
-
-    ```text
-    you@machine ~ $ ssh-keygen -t rsa -b 4096 -C "me@examplecom"
-    you@machine
-    Generating public/private rsa key pair.
-    Enter file in which to save the key (/Users/yourname/.ssh/id_rsa):
-    Enter passphrase (empty for no passphrase):
-    Enter same passphrase again:
-    Your identification has been saved in /Users/yourname/.ssh/id_rsa.
-    Your public key has been saved in /Users/yourname/.ssh/id_rsa.pub.
-    The key fingerprint is:
-    SHA256:ki0TNHm8qIvpH7/c0qQmdv2xxhYHCwlpn3+rVhKVeDo USEFUL-COMMENT
-    The key's randomart image is:
