 <h2> What is GNOME Shell? </h2>
 <p>
-GNOME Shell is the biggest new feature of <a ref="http://www.gnome3.org/";>GNOME 3</a>.
-If you're using GNOME 3 right now, it's the big black bar at the top
-of your screen. It's also that "Activities" place you go to to switch
-tasks.
+GNOME Shell provides core user interface functions for the GNOME
+desktop, like switching to windows and launching applications. User
+interface elements provided by GNOME Shell include, among other
+things, the Panel at the top of the screen, the Activities Overview,
+and Message Tray at the bottom of the screen.
 </p>
 <h2> What are GNOME Shell Extensions? </h2>
 <p>
-GNOME Shell Extensions are things that you can add on to GNOME 3 and
-GNOME Shell, like Chrome Extensions or Firefox Addons.
+GNOME Shell extensions are small pieces of code written by third party
+developers that modify the way GNOME works. (If you are familiar
+with Chrome Extensions or Firefox Addons, GNOME Shell extensions
+are similar to them.) You can find and install GNOME Shell
+extensions using this website.
+</p>
+<p>
+Since extensions are created outside of the normal GNOME design and
+development process, they are are supported by their authors, rather
+than by the GNOME community. Some features first implemented as
+extensions will likely find their way into future versions of GNOME.
 </p>
 <h2> What can GNOME Shell Extensions do? </h2>
 <p>
 When you install a GNOME Shell Extension, this adds new functionality
 to your OS. Extensions may make small changes, like moving your clock
-to the right-hand side of the screen, or make big changes, like laying
-out the windows in the "Activities" mode in a different way.
+to the right-hand side of the screen, or make big changes, like
+arranging the windows in the Activities Overview in a different way.
 </p>
 <h2> Are GNOME Shell Extensions safe? </h2>
 <p>
-Because of the wide variety of changes that we want GNOME Shell
-Extensions to make, it's pretty tricky to make sure they're secure. We
-don't want to negatively impact your system, but note that GNOME Shell
-Extensions may cause slowdown or make your system crash. If you've
-installed an extension like this, please report it to the extension
-author &mdash; chances are they want to fix these problems, too!
+The code in a GNOME Shell extension becomes part of the core operating
+system; for this reason, the potential exists for an extension to
+causes system misbehavior, crashes, or even to have malicious
+behavior like spying on the user or displaying unwanted
+advertisements. Extensions uploaded to this site are carefully
+reviewed for malicious behavior before they are made available for
+download.
 </p>
 <p>
-As an additional security measure, every one of the extensions listed
-on this website has had its code personally reviewed by a GNOME Shell
-Developer to the best of their abilities to ensure that people can't
-steal system information or pop up ads.
+If you encounter problems with an extension, such as a crash, make
+sure to report the problem using the "Help! It didn't work!" link on
+the extension's page.
 </p>
 <h2> I don't think I have GNOME Shell. What can I do to get it? </h2>
 <p>
-The easiest way to get GNOME Shell along with GNOME 3 is to install a
-Linux distribution with GNOME 3 and GNOME Shell installed. See the <a
-href="http://www.gnome.org/getting-gnome/";>Getting GNOME</a> page on
+The easiest way to get GNOME Shell is to install a Linux distribution
+that provides GNOME 3. See the
+<a href="http://www.gnome.org/getting-gnome/";>Getting GNOME</a> page on
 the main GNOME site to learn how to grab a Linux distribution with
 GNOME 3.

+<h2 id="old-version"> I'm using GNOME 3 Why can't I install extensions?</h2>
 <p>
-Make sure you're using GNOME 3.2 or later, not GNOME 3.0, and make
-sure you have the "GNOME Shell Extension Integration" browser plugin
-enabled. GNOME 3.2 added the browser plugin and necessary hooks in
-GNOME Shell to make this website possible, so this website does not
-support and will never support integration with GNOME 3.0.
+Support for installing extensions from this website was first added in
+GNOME 3.2, so if you are using GNOME 3.0, you'll need to upgrade to a
+newer Linux distribution. You can check what version of GNOME is
+installed on your system using the "System Information" panel of
+"System Settings".  If you are using GNOME 3.2 or newer and
+installation still doesn't work, check to make sure that the "GNOME
+Shell Integration" plugin is installed and enabled in your browser
+preferences.
 </p>

 Note: there were some bugs in the browser plugin shipped in GNOME 3.2
