The easiest and quickest way:

All within BIAB

File: import the audio
open Audio edit
select marker mode: Audio chord wizard
check Auto marking
add a couple of bar lines from start that matches the song
bar lines are automatically added for the song, check if ok and adjust if necessary
use equalize tempos if you need to stabilize the tempo
run analyze and chords will be detected
switch to chord sheet
adjust chords and for song structure, e.g. verse/chorus with A/B markers
you're done if the pitch of the audio was ok smile

if not, you need to correct the pitch.
There is a pitch shift tool under Audio, but with limited functionality, i.e. if the pitch is drifting in the audio it will just be a compromise to minimize the flaws

There are other softwares that can correct the pitch where it is needed in the audio file.

I think it took me longer to write this than it would to get a first draft of the complete song with the audio + the added backing tracks.

I've used this feature quite a lot with older audio recordings and it's really good!
But there is always room for improvements ...
