The first line of the section you linked to is "The readme included in
the solution has more details, especially on what additional software
is required to build which parts of Python.", and 'readme' is a link
to the readme on h.p.o. :)

The readme *should* be fairly comprehensive as I rewrote it last year,
but it may still be lacking since I wrote it after doing regular
builds for a year or two. In particular, the Quick Start guide at the
very beginning of the readme should be enough to get you going.
Quick Start Guide
1. Install Microsoft Visual Studio 2015, any edition.
2. Install Subversion, and make sure 'svn.exe' is on your PATH.
3. Run "build.bat -e" to build Python in 32-bit Release configuration.
4. (Optional, but recommended) Run the test suite with "rt.bat -q".
That should be enough to build Python, OpenSSL, Tcl/Tk/Tix, and all
other external projects. One thing that might be a gotcha there, if
you're using a Command Prompt window that you opened before installing
SVN, you'll need to either adjust PATH manually or open a new Command
Prompt to get the PATH changes.

Perl is not necessary if you're using sources from svn.python.org
(which "build.bat -e" will do). You also no longer need to install
NASM. nmake.exe is part of Visual Studio (or the Windows SDK,

You don't need to use prepare_ssl.py if you use get_externals.bat.
The 'ssl' section of the readme should cover that (if it can be
clarified, please point out the problems to me!).
