-### Installation
-
-The GTK library, as well as all pre-requisites and many language bindings
-(e.g. 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.
-
-In order to use `vcpkg` packages, you first need to clone the `vcpkg`
-repository,
-
-```
-git clone https://github.com/Microsoft/vcpkg
-cd vcpkg
-.\bootstrap-vcpkg.bat
-```
-You can then install the GTK packages with
-```
-vcpkg install gtk:x64-windows
-```
-
-The part behind the colon ':' specifies the target. After this step, any
-project created in Visual Studio will now automatically see the GTK
-libraries.
-
-If you build from the command line using `CMake`, you need to tell `CMake`
-where to find the libraries. This is done by adding 
-
-```
--DCMAKE_TOOLCHAIN_FILE=[vcpkg root]\scripts\buildsystems\vcpkg.cmake
-```
-
-to the CMake options, where `vcpkg` root is the location where you cloned
-the `vcpkg` repository.
