+Windows
+=======
+
+Prerequisites
+-------------
+
+Make sure the following have been installed:
+
+  * Visual C++ 2013 Express or later, available for free
+    * http://www.visualstudio.com/downloads/download-visual-studio-vs#d-express-windows-8
+
+  * Chromium depot_tools
+    * http://www.chromium.org/developers/how-tos/depottools
+  * git
+    * Either use the mysygit installed by depot_tools
+    * Or install msys git: http://msysgit.github.io/ yourself
+  * Python 2.7.x (if you're not planning to use cygwin)
+    * available for free download at http://www.python.org/download/releases/
+    * make sure the installer changes your %PATH% environment variable to include the directory with the "python.exe" binary
+  * Cygwin (optional, but useful if you want to use git)
+    * Download from  http://cygwin.org/setup.exe
+    * use any mirror you like; http://lug.mtu.edu works well
+    * Cygwin installs a minimum of options. Add these packages if they aren't already selected:
+      * Devel git
+      * Devel subversion
+      * Editors vim
+        * to fix arrows in insert, copy /usr/share/vim/vim73/vimrc_example.vim to ~/.vimrc
+      * Net ca-certificates
+      * Python python
+      * Utils patch
+      * Utils util-linux
+    * set the windows envionment variable CYGWIN to nodosfilewarning

+
+Generate Visual Studio projects
+-------------------------------
+
+We use the open-source gyp tool to generate Visual Studio projects (and
+analogous build scripts on other platforms) from our multi-platform "gyp"
+files.
+
+You can generate the Visual Studio projects by running gyp_skia, as follows:
+
+    cd %SKIA_CHECKOUT_DIR%
+    python gyp_skia
+
+This will produce Visual Studio projects in the `%SKIA_CHECKOUT_DIR%\out` directory.
+
+Build and run tests from the command line
+-----------------------------------------
+
+    ninja -C out\Debug dm
+    out\Debug\dm
+
+Normally you should run tests in Debug mode (SK_DEBUG is defined, and debug
+symbols are included in the binary). If you would like to build the Release
+version instead:
+
+    ninja -C out\Release dm
+    out\Release\dm
+
+Build and run tests in the Visual Studio IDE
+--------------------------------------------
+
+  * Generate the Visual Studio project files by running gyp_skia as described above
+  * Open a File Explorer window pointing at the %SKIA_CHECKOUT_DIR%\out\gyp directory
+  * Double-click on dm.sln to start Visual Studio and load the project
+  * When Visual Studio starts, you may see an error dialog stating that "One or more projects in the solution were not loaded correctly"... but there's probably nothing to worry about.
+  * In the "Solution Explorer" window, right-click on the "dm" project and select "Set as StartUp Project".
+  * In the "Debug" menu, click on "Start Debugging" (or just press F5). If you get a dialog saying that the project is out of date, click on "Yes" to rebuild it.
+  * Once the build is complete, you should see console output from the tests in the "Output" window at lower right.
+
+Build and run SampleApp in Visual Studio
+----------------------------------------
+
+  * Generate the Visual Studio project files by running gyp_skia as described above
+  * Open a File Explorer window pointing at the %SKIA_INSTALLDIR%\trunk\out\gyp directory
+  * Double-click on SampleApp.sln
+  * When Visual Studio starts, you may see an error dialog stating that "One or more projects in the solution were not loaded correctly"... but there's probably nothing to worry about.
+  * In the "Debug" menu, click on "Start Debugging" (or just press F5). If you get a dialog saying that the project is out of date, click on "Yes" to rebuild it.
+  * Once the build is complete, you should see a window with various example graphics. To move through the sample app, use the following keypresses:
+    * right-arrow key: cycle through different test pages
+    * left-arrow key: cycle through rendering methods for each test page
+    * other keys are defined in SampleApp.cpp’s SampleWindow::onHandleKey() and SampleWindow::onHandleChar() methods
+
+Build and run nanobench (performance testbench) from the command line
+---------------------------------------------------------------------
+
+Since nanobench tests performance, it usually makes more sense to run it in Release mode.
+
+    ninja -C out\Release nanobench
+    out\Release\nanobench
