 ## Connecting to an iFarm node
 
+Before connecting to an iFarm node, you must first connect to the login node via -
+
+```console
+ssh [email protected]
+```
+Where you should replace USER with your username. You will be prompted to enter your password. For the login node this is your PIN + two-factor token. Do not insert a space between the PIN and token. Once on the login node, you can then connect to an interactive node via -
+
+```console
+ssh USER@ifarm9
+```
+You will again be prompted for your password, this time, it's your CUE password.
+
+Other iFarm nodes can be specified if desired. Additionally, you can also just use -
+
+```console
+ssh -J [email protected] USER`@ifarm9
+```
+to do both steps at once.
