Step 2: Generating a SSH key

SSH keys are used to safely connect to remote machines, without a password, among other things. 
 If you already have a SSH key, you can skip to the next step. 
 We are going to generate a SSH key. (no clue how that works on windows!) 
 Linux 
 On Linux, simply type ssh-keygen -t ed25519 . 
Leave default location ( ~/.ssh/id_ed25519 ). 
For the password, you can leave it empty if you can guarantee that no one else will ever have access to that file, else set one.
