 * What's this?
 
-EasyPG is yet another GnuPG interface for Emacs.  It consists of three
-parts: transparent file encryption utility, Gnus/PGG backend, and
-elisp library to interact with GnuPG.
+EasyPG is yet another GnuPG interface for Emacs.  It consists of two parts:
 
-* Requirements
+- "The EasyPG Assistant" which provides basic GUI of GnuPG
+- "The EasyPG Library" which enables use of various features of GnuPG
+
+NOTE: EasyPG is neither a fork nor a re-implementation of Gnus/PGG.
 
-** GNU Emacs 21.4 or later, XEmacs 21.4 or later
+* Requirements
 
-** GnuPG 1.4.3 or later
+** GNU Emacs 21.4 or XEmacs 21.4
 
-** Gnus 5.10.8 or later (optional)
+** GnuPG 1.4.3
 
 * Quick start
 
 ** Installation
 
-$ ./configure
-$ sudo make install
-
-** Transparent file encryption utility
-
-EasyPG provides transparent file encryption utility similar to
-crypt++, alpaca.el, hedgehog.  To try this, add the following line to
-your ~/.emacs and C-x C-f ~/test.txt.gpg.
-
-(require 'epf)
+  $ ./configure
+  $ sudo make install
 
-** Gnus/PGG backend
+Add the following line to your ~/.emacs
 
-EasyPG provides an implementation of the backend interface of
-Gnus/PGG.  To use EasyPG instead of pgg-gpg, install pgg-epg.el and
-add the following line to your ~/.gnus.
+  (require 'epa-setup)
 
-(setq pgg-scheme 'epg)
+Then you can browse your keyring by M-x epa-list-keys.  In addition,
+you can do some cryptographic operations on dired.
 
-* Advantages over other competitors
-
-There are many competitors of EasyPG such as Mailcrypt, Gnus/PGG,
-gpg.el, etc.  EasyPG has some advantages over them.
-
-** EasyPG avoides potential security flaws of Emacs
-
-See "Security consideration" section.
-
-** GnuPG features are directly accessible from Emacs
-
-Other competitors provide only specific features of GnuPG since they
-still support PGP 2.*, 5.*, 6.*.  As the name indicates, EasyPG is
-inspired by GPGME (GnuPG Made Easy), and the library interface is
-close to GPGME.  With EasyPG you can benefit from a lot of features of
-GnuPG.

+If Emacs crashes and dumps core, passphrase strings in memory are also
 dumped within the core file.  `read-passwd' function clears passphrase
 strings by `(fillarray string 0)'.  However, Emacs performs compaction
 in gc_sweep phase.  If GC happens before `fillarray', passphrase
 strings may be moved elsewhere in memory.
