+How to set up an SSH key and use it to access a remote machine.
+
+### Generate Key
+
+``` bash
+ssh-keygen
+```
+
+### Copy the Key
+
+``` bash
+ssh-copy-id [-p port_nbr] username@server_or_IP
+```
+
+So this may look like one of the below.
+
+``` bash
+ssh-copy-id sftp@12.34.56.78
+ssh-copy-id -p 2222 leethaxor@pwnnoobs.pro
+```
+
+### Profit
+
+Now you should be able to log in or copy files without needing to type a password.
+
+```
+ssh [-p port_nbr] username@server_or_IP
+scp [-P port_nbr] username@server_or_IP:file_to_pull local_path_to_save
+scp [-P port_nbr] local_path_to_send username@server_or_IP:remote_path_to_save
+```
