-        * put these files anywhere
-        * python 2.7.x such as from python.org
-        * run get_python_architecture.py to make sure you know whether to download the following in 32-bit or 64-bit  
-        Administrator Command Prompt (to find it in Win 10, right-click windows menu)
-        * update python package system:
-```
-C:\python27\python -m pip install --upgrade pip wheel setuptools
-```
-        * numpy such as can be installed via the easy unofficial installer wheel at  
-        http://www.lfd.uci.edu/~gohlke/pythonlibs/#numpy  
-        then:
-```
-#cd to the folder where you downloaded the whl file
-C:\python27\python -m pip install "numpy-1.10.4+mkl-cp27-cp27m-win32.whl"  
-```
-        (but put your specific downloaded whl file instead)  
-        * Pillow (instead of PIL (Python Imaging Library) which is a pain on Windows): there is a PIL installer wheel for Python such as 2.7 here:  
-        http://www.lfd.uci.edu/~gohlke/pythonlibs/  
-        as suggested on http://stackoverflow.com/questions/2088304/installing-pil-python-imaging-library-in-win7-64-bits-python-2-6-4

-        (but put your specific downloaded whl file instead, such as Pillow-3.1.1-cp27-none-win_amd64.whl)
-        * run (or if your python executable does not reside in C:\Python27\ then first edit the file):
-```
-chunkymap-regen-loop.bat
-```
-        (all the batch does is run C:\Python27\python generator.py)
-        (generator.py will ask for configuration options on first run and ask for your www root)
+    (the installer will automatically download and install numpy and Pillow -- see also install-on-windows-manually.md)
 
 ## Known Issues
 * webapp: save selected world to a config file (click world on first visit to write initial config) instead of being silently autoselected
