 SSH is a connection tool.
 You need a public and private key generated by a command.
+This key is used for facilitating connections.
 
 SSH has several important files:
 
 - .ssh/config <- On this later
-- .ssh/key (private) .ssh/key.pub
+- .ssh/key (a private key, don't send this to anyone for any reason), and .ssh/key.pub (a PUBlic key, distribute as you wish)
 - .ssh/known_hosts <- Records of prior connections, may be invalidated or deleted
 . .ssh/authorized_keys <- list of public keys (literally cat of the .pub) allowed to SSH into this user, never provided by default
