 #  Build on Windows with Visual Studio IDE:
 
 (*Tested with VS 2017*)
+Ensure [CMake and c/c++ support options](https://docs.microsoft.com/en-us/visualstudio/install/modify-visual-studio?view=vs-2019) are installed along with Visual studio.
+
+The easyest way to proceed is to open a visual studio command prompt, and issue commands manually. Once dependencies are build and vkvg project files have been created, you may use the ide.
 
 #### Build dependencies
+Install the latest [vulkan sdk](https://vulkan.lunarg.com/) from lunarg.
+
 Make sure that [Git](https://git-scm.com/download/win) is installed on your machine by typing on the command line (cmd):
 ```bash
 > git --version
 git version 2.19.1.windows.1
 ```
-Install [vcpkg package manager](https://docs.microsoft.com/en-us/cpp/build/vcpkg?view=vs-2019) to build all required build dependencies:
+Install [vcpkg package manager](https://docs.microsoft.com/en-us/cpp/build/vcpkg?view=vs-2019) to build required libraries:
 ```bash 
 git clone https://github.com/Microsoft/vcpkg.git
 cd vcpkg
 .\bootstrap-vcpkg.bat
 ```
-Then install the libraries required by vkvg:
+Then install the libraries required by vkvg, use the triplet corresponding with your architecture:
 ```bash 
-vcpkg install fontconfig freetype harfbuzz vulkan
+vcpkg install fontconfig:x64-window freetype:x64-window harfbuzz:x64-window
 ```
 Optionaly, install [GLFW] to build the samples:
 ```bash 
-vcpkg install glfw
+vcpkg install glfw:x64-window
+```
+Add the path to the shared libraries binaries to your **PATH** environment variable, they are in %vcpkg-root%/installed/x64-windows/bin/.
+
+To make those libraries available for vsstudio use the [system wide integration](https://vcpkg.readthedocs.io/en/latest/examples/installing-and-using-packages/#vsmsbuild-project-user-wide-integration) from vcpkg.
+```bash 
+vcpkg integrate install
 ```
 #### CMake configuration
-Exit vcpkg directory and clone the vkvg repository:
+Exit vcpkg directory and clone the vkvg repository and its submodule vkh:
 ```bash
 git clone --recursive https://github.com/jpbruyere/vkvg.git
 cd vkvg
 #create a build directory
 mkdir build
 ```
-To generate the solution file (.sln), use CMake IDE. Select the vkvg root folder as the source directory and the build folder we've just create in it.
-
-Configure the project and select the target build. (*for VS17 it should be something like `Visual Studio 15 2017 Win64`*).
-
-Also specify the **toolchain file** for cross-compiling provided by **vcpkg** (*C:\...\vcpkg\scripts\buildsystems\vcpkg.cmake*).
-
-On the bottom of the GUI there are some options related with the **vkvg** library. Unselect the **VKVG_LCD_FONT_FILTER** (FreeType is built without [lcd fonts](https://en.wikipedia.org/wiki/Subpixel_rendering) by default).
-
-Now generate the sln project and procede to open the project with Visual Studio.<br>
-
-#### Build vkvg
-To build the project (the **ALL BUILD** project should be the Start Up project) press **F7** or press build (top of the screen) and then press build solution. If everything goes well you finally have the .lib and .dll files to use in our projects. These files can be found in the *C:\...\vkvg\build\CMakeFiles\Debug* directory.
+To generate the solution file (.sln) from the build directory we use cmake with the toolchain file provided by vcpkg and we also disable the lcd font filtering (FreeType is built without [lcd fonts](https://en.wikipedia.org/wiki/Subpixel_rendering) by default).
+```
+cmake .. -DCMAKE_TOOLCHAIN_FILE=..\..\vcpkg\scripts\buildsystems\vcpkg.cmake -DVKVG_LCD_FONT_FILTER=off
+```
+To adjust later compilation options, you may recall cmake command, or use the cmake-gui command.
+```bash
+cmake-gui ..
+```
+Now you should have the vkvg.sln and all the projects file into your build directory. You may build the complete solution on the command line with:
+```bash
+msbuild vkvg.sln
+```
