After some complains from a dyslexic user, I decided to make 2 pretty minor changes
Section 3, step 1 - changed "all safety checks" to "all checks" - safeb9sinstaller just calls them "checks", so the word safety there was unneeded
Section 3, step 2 - changed "key combo given to install..." to "key combo given on the top screen to install..." - this specifically calls out where the combo will be given, to prevent users from looking at the bottom screen when the combo is on the top.
