+@cindex using gpg
+
+Gnus has an ALPHA support to GPG that's provided by @file{gpg.el} and
+@file{mml2015.el}. When viewing signed or encrypted messages, Gnus automatically
+asks if you want to verify or decrypt them.
+
+To use this correctly with GPG, you'll need the following lisp code in your
+@file{~/.emacs} or @file{~/.gnus}:
+
+@lisp
+(setq mml2015-use 'gpg)
+(setq gpg-temp-directory "~/.gnupg/tmp")
+@end lisp
+
+The @code{gpg-temp-directory} need to point to a directory with permissions set
+to 700, for your own safety.
+
+If you want to benefit of PGP2.6 compatibility, you might create a script named
+@file{gpg-2comp} with these instructions:
+
+@code{
+#!/bin/sh
+exec gpg --rfc1991 \"\$\@\"
+}
+
+If you don't want to use such compatibility, you can add the following line to
+your @file{~/.emacs} or @file{~/.gnus}:
+
+@lisp
+(setq gpg-command-default-alist (quote ((gpg . "gpg") (gpg-2comp . "gpg"))))
+@end lisp
+
+To sign or encrypt your message you may choose to use the MML Security menu or
+@kbd{M-m s p} to sign your message using PGP/MIME, @kbd{M-m s s} to sign your
+message using S/MIME. There's also @kbd{M-m c p} to encrypt your message with
+PGP/MIME and @kbd{M-m c s} to encrypt using S/MIME.
+
+Gnus will ask for your passphrase three times and then it will send your
+message, if you've typed it correctly.
