 Compiling on Windows
 ====================
-Users are advised to use the Visual Studio .sln file in the win/ folder.
-For Windows users a prebuilt Open CASCADE version is available from the
-http://opencascade.org website. Download and install this version and
-provide the paths to the Open CASCADE header and library files to MS
-Visual Studio C++.
+Users are advised to build IfcOpenShell using the CMake file provided in
+the cmake/ folder.

-For building the Autodesk 3ds Max plugin, the 3ds Max SDK needs to be
-installed as well as 3ds Max itself. Please provide the include and
-library paths to Visual Studio.
+The preferred way to fetch and build this project's dependencies is to use the build scripts
+in win/ folder. See [win/readme.md] for more information. Instructions in a nutshell
+(assuming Visual Studio x64 environment variables set):
+    > git clone https://github.com/IfcOpenShell/IfcOpenShell.git
+    > cd oce\win
+    > build-deps.cmd (defaults to using VS 2015 x64 RelWithDebInfo build)
+    > run-cmake.bat (defaults to using VS 2015 x64)
+    > ..\build-vs2015-x64\IfcOpenShell.sln
+You can now build the solution using the RelWithDebInfo configuration (freshly created solution by CMake defaults to Debug).
+Build the INSTALL project to deploy the headers and binaries into a single location if wanted/needed.

-For building the IfcPython wrapper, SWIG needs to be installed. Please
-download the latest swigwin version from http://www.swig.org/download.html.
-After extracting the .zip file, please add the extracted folder to the PATH
-environment variable. Python needs to be installed, please provide the
-include and library paths to Visual Studio.
+Alternatively, the old Visual Studio solution and project files requiring manual work can
+be found from the win/sln folder.

+Windows Build Tools and Scripts
+===============================
+This folder contains build tools and script for automatic building and deployment of IfcOpenShell (IFCOS)
+and its dependencies.
+
+As a general guideline, `.cmd` files are non-standalone batch files that need to be run from command
+prompt or from another batch file, and/or while the Visual Studio environment variables set, and `.bat` files are
+standalone batch files that can be run also e.g. from the File Explorer.
+
+Usage Instructions
+------------------
+Execute `build-deps.cmd` to fetch, build and install the dependencies. The batch file will print
+the requirements for a successful execution. The script allows a few user-configurable build options
+which are listed in the usage instructions. Either edit the script file or set these values before
+running the script.
+
+`build-deps.cmd` expects a CMake generator as `%1` and a build configuration type as `%2`. If the parameters
+are not provided, the default values are used (`"Visual Studio 14 2015 Win64"` and `RelWithDebInfo` respectively).
+A build type (`Build/Rebuild/Clean`) can be provided as `%3`, if wanted (defaults to `Build`). See `vs-cfg.cmd`
+if you want to change the defaults. The batch file will create `deps\` and `deps-vs<VERSION>-<ARCHITECTURE>-installed\`
+directories to the project root. Debug and release builds of the depedencies can co-exist by simply running
+`build-deps.cmd <GENERATOR> Debug` and `build-deps.cmd <GENERATOR> <Release|RelWithDebInfo|MinSizeRel>`.
+
+After the dependencies are build, execute `run-cmake.bat`. The batch file expects a CMake generator as
+`%1` (if not provided, the same default value as above is used), or alternatively, if more parameters are provided, `%*` is passed for the CMake invokation, i.e., if one 
+wants to pass custom build options, the generator must be passed also using CMake's syntax:
+
+`run-cmake.bat -G "Visual Studio 14 2015 Win64" -DBUILD_IFCPYTHON=0`.
+
+The batch script will create a folder of form `build-vs<VERSION>-<ARCHITECTURE>\` which will contain the solution and project files for Visual Studio.
+**If you wish to use any library from a custom location, modify the paths in run-cmake.bat 
+accordingly**.
+
+After this, one can build the project using the `IfcOpenShell.sln` file in the build folder. Build the `INSTALL` project
+if wanted. The project will be installed to `installed-vs<VERSION>-<ARCHITECTURE>\` folder in the project's root
+folder and the required IfcOpenShell-Python parts are deployed to the `<PYTHONPATH>\Lib\site-packages\` folder.
+
+**Note:** All of the dependencies are build as static libraries against the static run-time allowing the developer
+to effortlessly deploy standalone IFCOS binaries.
+
+
+Directory Structure
