+@section Sample Session
+
+This is an example ERC session which shows how to connect to the #emacs
+channel on Freenode. Another IRC channel on Freenode that may be of
+interest is #erc, which is a channel where ERC users and developers hang
+out.
+
+@itemize @bullet
+
+@item Connect to Freenode
+
+Run @kbd{M-x erc}. Use ``irc.freenode.net'' as the IRC server, ``6667''
+as the port, and choose a nickname.
+
+@item Get used to the interface
+
+Switch to the ``irc.freenode.net:6667'' buffer, if you're not already
+there. You will see first some messages about checking for ident, and
+then a bunch of other messages that describe the current IRC server.
+
+@item Join the #emacs channel
+
+In that buffer, type ``/join SPC #emacs'' and hit @kbd{RET}. Depending
+on how you've set up ERC, either a new buffer for ``#emacs'' will be
+displayed, or a new buffer called ``#emacs'' will be created in the
+background. If the latter, switch to the ``#emacs'' buffer. You will
+see the channel topic and a list of the people who are currently on the
+channel.
+
+@item Register your nickname with Freenode
+
+If you would like to be able to talk with people privately on the
+Freenode network, you will have to ``register'' your nickname. To do
+so, switch to the ``irc.freenode.net:6667'' buffer and type ``/msg
+NickServ register <password>'', replacing ``<password>'' with your
+desired password. It should tell you that the operation was successful.
+
+@item Talk to people in the channel
+
+If you switch back to the ``#emacs'' buffer, you can type a message, and
+everyone on the channel will see it.
+
+@item Open a query buffer to talk to someone
+
+If you want to talk with someone in private (this should usually not be
+done for technical help, only for personal questions), type ``/query
+<nick>'', replacing ``<nick>'' with the nickname of the person you would
+like to talk to. Depending on how ERC is set up, you will either see a
+new buffer with the name of the person, or such a buffer will be created
+in the background and you will have to switch to it. Begin typing
+messages, and you will be able to have a conversation.
+
+Note that if the other person is not registered, you will not be able to
+talk with them.

+@section Special Features
+
+ERC has some features that distinguish it from some IRC clients.
+
+@itemize @bullet
+
+@item multiple channels and multiple servers
+
+Every channel is put in a separate buffer. Several IRC servers may be
+connected to at the same time.
+
+@cindex query buffers
+@item private message separation
+
+Private conversations are treated as channels, and are put into separate
+buffers in Emacs. We call these ``query buffers''.
+
+@item highlighting
+
+Some occurences of words can be highlighted, which makes it easier to
+track different kinds of conversations.
+
+@item notification
+
+ERC can notify you that certain users are online.
+
+@item channel tracking
+
+Channels can be hidden and conversation continue in the background. You
+are notified when something is said in such a channel that is not
+currently visible. This makes it easy to get Real Work done while still
+maintaining an IRC presence.
+
+@item nick completion
+
+ERC can complete words upon hitting @kbd{TAB}, which eases the writing
+of nicknames in messages.
+
+@cindex history ring
+@item history
+
+Past actions are kept in history rings for future use. To navigate a
+history ring, hit @kbd{M-p} to go backwards and @kbd{M-n} to go
+forwards.
+
+@item multiple languages
+
+Different channels and servers may have different language encodings.
+
+In addition, it is possible to translate the messages that ERC uses into
+multiple languages. Please contact the developers of ERC at
+@email{erc-discuss@@gnu.org} if you are interested in helping with the
+translation effort.
+
+@item user scripting
+
+Users can load scripts (e.g. auto greeting scripts) when ERC starts up.
+
+It is also possible to make custom IRC commands, if you know a little
+Emacs Lisp. Just make an Emacs Lisp function and call it
+@code{erc-cmd-NEWCOMMAND}, where @code{NEWCOMMAND} is the name of the
+new command in capital letters.
+
+@item auto reconnect
+
+If the connection goes away at some point, ERC will try to reconnect
+automatically. If it fails to reconnect, and you want to try to
+manually reestablish the connection at some later point, switch to an
+ERC buffer and run the @code{/RECONNECT} command.
