Confused with "shell application with SSH"

[wirawan0]

In this section of episode "Connecting to a remote HPC system", under subheading titled "Better Security With SSH Keys", I found the first paragraph to be confusing: It says

The Lesson Setup provides instructions for installing a shell application with SSH. If you have not done so already, please open that shell application with a Unix-like command line interface to your system.

I am confused and have this question: what does it mean with "installing a shell application with SSH"? SSH can't be used to install any shell application, can it? It seems that it reads better in this way: "installing a shell application for SSH".

What is the point of that paragraph? Do you want to make sure that learners have an SSH client available on their own computer? Or something else? To be more logical, that paragraph should go right above the subheading, just before the "Better Security ...".
