+### Windows
+
+You need Python 
+[2.7 32 bit](https://www.python.org/downloads/release/python-2718/).
+Download the `Windows x86 MSI installer` 
+and be sure to add `python` to `PATH` during installation.
+
+You can run `mangle` using 64 bit Python 2.7,
+but won't be able to build a binary with `py2exe`,
+and any performance difference is negligible.
+
+Install virtualenv globally, if you don't already have it.
+
+```
+> pip install virtualenv
+```
+
+and install all dependencies in a venv in the mangle directory, e.g.
+
+```
+...\mangle> virtualenv venv
+> venv\Scripts\activate
+(venv) > pip install Pillow
+(venv) > pip install reportlab
+```
+
+It can be pretty difficult to install PyQT4 from source,
+so prebuilt binaries are available at
+http://www.lfd.uci.edu/~gohlke/pythonlibs/#pyqt4
+
+You need 
+`PyQt4-4.11.4-cp27-cp27m-win32.whl`
+
+which you can install after placing the file
+in the `mangle` folder via
+
+```
+(venv) > pip install PyQt4-4.11.4-cp27-cp27m-win32.whl
+```
+
+So your final `pip freeze` can look like:
+
+```
+(venv) > pip freeze
+Pillow==6.2.2
+PyQt4 @ file:///.../mangle/PyQt4-4.11.4-cp27-cp27m-win32.whl
+reportlab==3.5.59
+```
+
+#### Optional
+
+To actually build a stand-alone `.exe`, install
+
+```
+(venv) > pip install py2exe_py2
+```
+
+and install 
+[Microsoft Visual C++ Compiler for Python 2.7](https://www.microsoft.com/en-us/download/details.aspx?id=44266)
+
+A standalone binary can be created in the `dist` folder via
+
+```
+(venv) > python setup.py install
+```
+
+You may get an error which can be solved by looking at
+https://stackoverflow.com/questions/38444230/error-converting-gui-to-standalone-executable-using-py2exe
