a few questions:

i am confused by this line:

You need a Nerd Font. The prompt uses Nerd Font glyphs for the git branch, the language logos and the prompt character. Without one, those show as empty boxes.

this sounds like a nerdfont needs to be installed manually. but that doesn't seem to be the case because it just seems to work. and i don't remember installing such a font.

i also wonder what version it is showing when not in a git repo directory.

finally, how do i edit history entries before rerunning them?
