 This description will be updated during the development process.
 
-At the moment there is nothing to build.

 ## Requirements
 Most of external libraries will be located directly in the source code, to reduce a number of dependencies and make building faster.
 But this libraries and tools you have to install by yourself:
 - CMake
 - CUDA
 - OptiX
-- optionally OpenVDB if you want to load .vdb files with volumetric data.

+## Building for Windows
+Windows is the only one platform, which is supported at the moment.
+Building should be as simple as creating a folder for build files and calling CMake, something like:
+```
+cmake -G "Visual Studio 17 2022"  ..
+```
