Its an elaborate instruction on how to trick users into downloading Chrome and making all the UI, installation dialogs, etc., make it look like it should be IE 11 (presumably, only until the point where you actually get Chrome open), including installing IE 11 icons, written in a way to trick the person
following the instructions (but only if that person is exceptionally trusting) into thinking that they are actually getting the users that hit their site to upgrade to IE 11.
I'm guessing that the OP knows exactly what they are doing.
