You can start emacsclient from within emacs with the command 

          M-x server-start.  

(or add the expression `server-start' to your .emacs to start it
automatically).  Emacsclient listens for calls from other programs to
use an already-running emacs as editor, and tells that already-running
emacs session to visit a file whose name is specified in the call from
the other program.

So that part (setting up the `server' on the emacs side) is very easy.

To get other programs to use emacsclient, it is often enough to set
the environment variable EDITOR to `emacsclient' (say in .bash_profile
if you use bash). A lot of programs will let you set a more specific
environment variable. Mutt, for instance, allows you to:

          set editor=emacsclient

in .muttrc so that it will always call a running emacs as its editor.

When you've finished editing the file, the command Ctl-x # saves the
changes and sends a message back to emacsclient to exit. The
cooperating program waits for emacsclient to exit. 

You can find full documentation in `Using Emacs as a Server' in the
Info system,
