How to use Gnus with newsgroup like Google Group?

Question

I tried this setting:

(setq gnus-select-method '(nnml "comp.lang.lisp"))

But when I activate Gnus, no grouop is shown. How do I add groups like comp.lang.*?

Edit: I tried with nntp:

(setq gnus-select-method '(nntp "comp.lang.lisp"))

but it doesn't work:

Warning: Opening nntp server on comp.lang.lisp...failed: ; Server nntp+comp.lang.lisp previously determined to be down; not retrying

Expanding on @logoscia's comment, comp.lang.lisp isn't an NNTP server, but a newsgroup. You can use Gmane/Gwene to read mailing lists and RSS feeds via NNTP. You can also add a traditional news server, like news.eternal-september.org. The elisp snippet below can get you started.

(setq gnus-select-method '(nnml "")) ;; this depends on how you want
                                     ;; to get your mail
(setq gnus-secondary-select-methods '((nntp "news.gmane.org")
                                      (nntp "news.eternal-september.org")))

Start Gnus with M-x gnus. In the group buffer hit ^ to get to the *Server* buffer then browse the newsgroups on the servers. From there you can subscribe/unsubscribe to newsgroups with u. Back in the *Group* buffer you will see your subscribed groups. For details, see the Gnus manual.
