-*  Works best with Python 3.4, due to virtualenv and pip batteries included. Python3+ required for fetch command.
-*  Check config.py for virtual env paths, suffix for 64-bit releases. Defaults to `x64`, set `X64_EXT` to change.
-*  When running in CI with one Python per invocation, set the `PYTHON` env variable to the Python folder. (e.g. `PYTHON`=`c:\Python27\`) This overrides the matrix in config.py and will just build and test for the specific Python.
-* `python get_pythons.py` downloads all the Python releases, and their signatures. (Manually) Install in `c:\PythonXX[x64]\`.
-* `python build_dep.py` downloads and creates a build script for all the dependencies, in 32 and 64-bit versions, and with both compiler versions.
-* (in powershell) `build_deps.cmd` invokes the dependency build.
-* `python build.py --clean` makes Pillow for the matrix of Pythons.
-* `python test.py` runs the tests on Pillow in all the virtual envs.
-*  Currently working with zlib, libjpeg, freetype, and libtiff on Python 2.7, and 3.4, both 32 and 64-bit, on a local win7 pro machine and appveyor.com
-* WebP is built, not detected.
-* LCMS, OpenJPEG and libimagequant are not building.

+* Requires Microsoft Visual Studio 2017 or newer with C++ component.
+* Requires NASM for libjpeg-turbo, a required dependency when using this script.
+* Requires CMake 3.13 or newer.
+* Python 3.6+ is required to generate valid scripts, but builds targeting Python 3.5+ are supported.
+* Tested on Windows Server 2016 with Visual Studio 2017 Community (AppVeyor).
