using gnus to read mail in existing Maildir

[Micha Feigin]

I have my mail currently delivered to a Maildir in my home directory,
currently accessed using mutt.

I was thinking to check out gnus for reading mail, but I can't figure
out for the manual how and if its possible to access the mail in the
maildir in place (it seems so using nnmaildir but that part of the
manual seems as unreadable as they come in term of actually
implementing what it says).

Thanx
