-<h3>Installing GTK and its dependencies</h3>
-
-<p>The easiest way to install GTK and its dependencies in binary form is through the <a class="external" 
href="https://msys2.github.io/";>MSYS2</a> project. MSYS2 provides a UNIX-like development environment for 
Windows. It provides packages for many software applications and libraries, including the GTK stack. These 
packages are installed using the <a class="external" 
href="https://github.com/msys2/msys2/wiki/MSYS2-installation#iv-general-package-management";>pacman package 
manager</a>.</p>
-
-<p>Note: in the following steps, we'll assume you're using a 64-bit Windows. Therefore, the package names 
include the <code>x86_64</code> architecture identifier. If you're using a 32-bit Windows, please adapt the 
instructions below using the <code>i686</code> architecture identifier.</p>
+<p>Note: These instructions are intended for developers wanting to
+create Windows applications based on GTK, not for end-users. On
+Windows, GTK applications are typically bundled with GTK already, so
+end-users do not need to worry about how to install GTK itself.</p>
+
+<p>There are two methods to install GTK on Windows development
+machines. One method is based on the packages available from the <a
+href="https://docs.microsoft.com/en-us/cpp/vcpkg";>Microsoft vcpkg
+project</a>, which are built using Visual Studio, and therefore work
+well if you intend to develop using that platform. The other method is
+based on the packages provided by <a
+href="https://www.msys2.org/";>MSYS2</a>, which provides a UNIX-like
+environment for Windows. Both of these repositories also provide
+packages for a large number of other useful open source libraries.</p>
+
+<p>(If you really want to build GTK from the pristine sources
+yourself, you can use the project files for Microsoft Visual Studio
+provided by the GTK releases. Learn more on <a class="external"
+href="https://wiki.gnome.org/Projects/GTK/Win32/MSVCCompilationOfGTKStack";>how
+to build the GTK stack using Microsoft Visual Studio</a> and read
+these other tips on <a class="external"
+href="https://blogs.gnome.org/nacho/2015/02/19/building-gtk-3-with-msvc-2013/";>how
+to build GTK with MSVC on Windows</a>. In almost all cases, using the
+packages from vcpkg or MSYS2 is much simpler though.)</p>
+
+<p>These instructions all assume you are using Windows 7 or later. For
+older versions of Windows, you will need to do a custom build of older
+versions of GLib and GTK.</p>
+
+
+<h2><a name="Vcpkg">Using GTK from vcpkg packages</a></h2>
+
+<h3>Installation</h3>
+
+<p>The GTK library, as well as all pre-requisites and many language
+bindings (e.g.&nbsp;the C++ bindings gtkmm) are packaged by the
+Microsoft vcpkg project for use with Visual Studio. This provides a
+very simple way to setup a development environment to create GTK
+apps. If you prefer a more UNIX-like experience, building from the
+command line instead of using Visual Studio, you may want to consider
+installing GTK from MSYS2 instead.</p>
+
+<p>In order to use vcpkg packages, you first need to clone the vcpkg repository,<br/>
+<code>git clone https://github.com/Microsoft/vcpkg<br/>
+cd vcpkg<br/>
+.\bootstrap-vcpkg.bat</code>
+You can then install the GTK packages with<br/>
+<code>vcpkg install gtk:x64-windows<br/></code><br/>
+The part behind the colon ':' specifies the target. After this step, any 
+project created in Visual Studio will now automatically see the GTK libraries.</p>
+
+<p>If you build from the command line using CMake, you need to tell CMake where
+to find the libraries. This is done by adding<br/>
+<code>-DCMAKE_TOOLCHAIN_FILE=[vcpkg root]\scripts\buildsystems\vcpkg.cmake</code><br/>
+to the CMake options, where <code>vcpkg root</code> is the location where
+you cloned the vcpkg repository.</p>
+
+<h3>Building and distributing your application</h3>
+
+<p> Once you install GTK as above, you should have little problem
+compiling a GTK app. In order to run it successfully, you will also
+need a GTK theme.  There is some old builtin support for a Windows
+theme in GTK, but that makes your app look like a Windows&nbsp;7
+app. It is better to get a Windows&nbsp;10 theme, for instance the <a
+href="https://github.com/B00merang-Project/Windows-10";>Windows 10
+Transformation Pack</a>.</p>
+
+<p> Copy the <code>gtk-3.20</code> folder of that repository to a
+folder <code>share/themes/Windows10/gtk-3.0/</code> in your
+installation folder. You also need to copy the icons from the Adwaita
+theme, which you can get from Linux box, where they are stored in
+<code>/usr/share/icons/Adwaita/</code>; copy this entire folder to a
+<code>share/icons</code> folder in your installation folder. Ditto for
+the hicolor icons. To make GTK pick up this theme,
+put a file <code>settings.ini</code> in <code>etc/gtk-3.0</code>
+in your installation folder. This should contain<br/>
+<code>[Settings]<br/>
+gtk-theme-name=Windows10<br/>
+gtk-font-name=Segoe UI 9<br/></code><br/>
+And to top it all off, find the <code>gschemas.compiled</code> file
+in <code>/usr/share/glib-2.0/schemas/</code> and copy that to
+<code>share/glib-2.0/schemas</code>.</p>
+
+<p> You then zip up your installation folder, or use an installer
+generator to do that for you, and distribute the result.  </p>
