-@b{Important:} @i{If you the version of Org that comes with Emacs or as a
-XEmacs package, please skip this section and go directly to @ref{Activation}.
-If you downloaded Org as an ELPA package, please read the instructions on the
-@uref{http://orgmode.org/elpa.html, Org ELPA page}.  To see what version of Org
-(if any) is part of your Emacs distribution, type @kbd{M-x org-version} (if
-your Emacs distribution does not come with Org, this function will not be
-defined).}
-
-Installation of Org mode uses a build system, which is described in more
-detail on @uref{http://orgmode.org/worg/dev/org-build-system.html, Worg}.
-
-If you have downloaded Org from the Web as a distribution @file{.zip} or
-@file{.tar.gz} archive, take the following steps to install it:
+Org is part of recent distributions of GNU Emacs, so you normally don't need
+to install it.  If, for one reason or another, you want to install Org on top
+of this pre-packaged version, there are three ways to do it:
 
 @itemize @bullet
-@item Unpack the distribution archive.
-@item Change into (@code{cd}) the Org directory.
-@item Run @code{make help config}
-and then check and edit the file @file{local.mk} if the default configuration
-does not match your system.  Set the name of the Emacs binary (likely either
-@file{emacs} or @file{xemacs}), and the paths to the directories where local
-Lisp and Info files will be installed.  If the Emacs binary is not in your
-path, give the full path to the executable.  Avoid spaces in any path names.
-@item Run @code{make config}
-again to check the configuration.
-@item Run @code{make install} or @code{sudo make install}
-to build and install Org mode on your system.
+@item By using Emacs package system.
+@item By downloading Org as an archive.
+@item By using Org's git repository.
 @end itemize
 
-If you use a cloned Git repository, then the procedure is slightly different.
-The following description assumes that you are using the @code{master} branch
-(where the development is done).  You could also use the @code{maint} branch
-instead, where the release versions are published, just replace @code{master}
-with @code{maint} in the description below.
+We @b{strongly recommend} to stick to a single installation method.
 
-@itemize @bullet
-@item Change into (@code{cd}) the Org repository.
-@item Run @code{git checkout master}
-to switch to the @code{master} branch of the Org repository.
-@item Run @code{make help}
-and then check and edit the file @file{local.mk}.  You must set the name of
-the Emacs binary (likely either @file{emacs} or @file{xemacs}), and the paths
-to the directories where local Lisp and Info files will be installed.  If the
-Emacs binary is not in your path, you must give the full path to the
-executable.  Avoid spaces in any path names.
-@item Run @code{make config}
-to check the configuration.
-@item Optionally run @code{make test}
-to build Org mode and then run the full testsuite.
-@item Run @code{make update2} or @code{make up2}
-to update the Git repository and build and install Org mode.  The latter
-invocation runs the complete test suite before installation and installs only
-if the build passes all tests.
-@end itemize
+@subsubheading Using Emacs packaging system
 
-If you don't have access to the system-wide directories and you don't want to
-install somewhere into your home directory, you can run Org directly from the
-distribution directory or Org repository by compiling Org mode in place:
-
-@itemize @bullet
-@item Change into (@code{cd}) the Org repository.
-@item Run @code{git checkout master}
-to switch to the @code{master} branch of the Org repository.
-@item Run @code{make compile}
-@end itemize
+Recent Emacs distributions include a packaging system which lets you install
+Elisp libraries.  You can install Org with @kbd{M-x package-install RET org}.
+To make sure your Org configuration is well taken into account, initialize
+the package system with @code{(package-initialize)} before setting any Org
+option.  If you want to use Org's package repository, check out the
+@uref{http://orgmode.org/elpa.html, Org ELPA page}.
 
-Last but not least you can also run Org mode directly from an Org repository
-without any compilation.  Simply replace the last step in the recipe above
-with @code{make uncompiled}.
+@subsubheading Downloading Org as an archive
 
-Then add the following line to @file{.emacs}:
+You can download Org latest release from @uref{http://orgmode.org/, Org's
+website}.  In this case, make sure you set the load-path correctly in your
+@file{.emacs}:
 
 @example
 (add-to-list 'load-path "~/path/to/orgdir/lisp")
 @end example
 
-@noindent
-If you plan to use code from the @file{contrib} subdirectory without
-compiling them, do a similar step for this directory:
+The downloaded archive contains contributed libraries that are not included
+in Emacs.  If you want to use them, add the @file{contrib} directory to your
+load-path:
 
 @example
 (add-to-list 'load-path "~/path/to/orgdir/contrib/lisp" t)
 @end example
 
-If you want to include those files with the build and install, please
-customize the variable @code{ORG_ADD_CONTRIB} instead in your @code{local.mk}
-file, for more details please see this
-@uref{http://orgmode.org/worg/dev/org-build-system.html#sec-4-1-2,
-description on Worg}.
+Optionally, you can compile the files and/or install them in your system.
+Run @code{make help} to list compilation and installation options.
 
-Installing Info files is system dependent, because of differences in the
-@file{install-info} program.  The Info documentation is installed together
-with the rest of Org mode.  If you don't install Org mode, it is possible to
-install the Info documentation separately (you need to have
-install-info@footnote{The output from install-info (if any) is system
-dependent.  In particular Debian and its derivatives use two different
-versions of install-info and you may see the message:
+@subsubheading Using Org's git repository
+
+You can clone Org's repository and install Org like this:
 
 @example
-This is not dpkg install-info anymore, but GNU install-info
-See the man page for ginstall-info for command line arguments
+$ cd ~/src/
+$ git clone git://orgmode.org/org-mode.git
+$ make autoloads
 @end example
 
-@noindent which can be safely ignored.}
-on your system).
+Note that @code{make autoloads} is mandatory: it defines Org's version and
+Org's autoloaded functions, respectively in @file{org-version.el} and in
+@file{org-loaddefs.el}.
 
-@example
-make install-info
-@end example
+Remember to add the correct load-path as described in the method above.
 
-Do not forget to activate Org as described in the following section.
-@page
+You can also compile and install Org from this git repository: check
+@code{make help} to get the list of compilation/installation options.
+
+For more detailed explanations on Org's build system, please check the Org
+Build System page on @uref{http://orgmode.org/worg/dev/org-build-system.html, Worg}.
