I found these instructions here.
Good ideas:
Dear Beginner:
Here’s the Jeffrey Chappell step-by-step method for approaching a fake book lead sheet:
1. Play the melody with your right hand.
2. Play the melody with your right hand plus the roots of the chords with your left hand.
3. Play the melody with your right hand plus the chords, in root position, with your left hand.
4. Play the melody with your right hand plus the chords with your left hand, using root position as well as inversions to facilitate smooth connections.
(Tip: For descending fifth progressions, all the connections will be step-wise, making things easier. And there are bunches of descending fifth progressions in fake book tunes.)
That’s it. Congratulate yourself. You’re playing a tune from a fake book.
