How to open a file in nano

step one: open this file in nano

Seems like it showed me how to open nano and then just let go of the wheel.
How do I open a file in nano?

nano <filename>

Example, if file name is foo.txt

nano foo.txt

O I C.
I was opening that hello.txt file. I must’ve misunderstood the instructions. I see now that put simply, just type nano in front of whatever file you’re opening to open it in nano. thank you for your help.
