 key data structures and algorithms, which can be accessed through the [msdfgen.h](msdfgen.h) header.
 Extensions contain utilities for loading fonts and SVG files, as well as saving PNG images.
 Those are exposed by the [msdfgen-ext.h](msdfgen-ext.h) header. This module uses

 Additionally, there is the [main.cpp](main.cpp), which wraps the functionality into

-To build the project, you may use the included [Visual Studio solution](Msdfgen.sln)
-or [CMake script](CMakeLists.txt).
+To use the project as a library, you may install it via the [vcpkg](https://vcpkg.io) package manager as
+```
+vcpkg install msdfgen
+```
+Or, to build the project from source, you may use the included [CMake script](CMakeLists.txt).
+In its default configuration, it requires [vcpkg](https://vcpkg.io) as the provider for third-party library dependencies.
+If you set the environment variable `VCPKG_ROOT` to the vcpkg directory,
+the CMake configuration will take care of fetching all required packages from vcpkg.
