It's good you'll have more browsers. You can also use the other terminals that will be available on the computer you're installing.

Go with the framebuffer mode if you're able. It will give you more history on the screen as scrollback is going to be unavailable for a bit.

Alt+(F1,F2,F3,F4) are the switches for independent terminals.
So, you could do all your work on Terminal 1 and switch to Terminal 2 and read the manual with the text browser, "links". Caution, use only one window to execute the commands for the install. Once you "chroot", they'll be rooted in different locations.
I did it and it took (me) a while to realize the cause of all the subsequent errors...

Have fun!
