(OT) Setting up PINE or MUTT for IMAP?

Hello all: I've got a customer who would like to access his IMAP email via PINE or MUTT using a login account on the server that serves up his IMAP mail. He uses a Webmail type program now to access his mail, but on occassion would like to use a text based shell type email client. Could somebody point me to some good tutorials on how to configure PINE or MUTT to send/retrieve mail via a local IMAP server? Thanks, Jim
