+# Building on Windows
+
+There are a few possibilities to build matplotlib on Windows:
+
+* Wheels via [matplotlib-winbuild](https://github.com/jbmohler/matplotlib-winbuild)
+* Wheels by using conda packages
+* Conda packages
+
+## Wheel builds using conda packages
+
+This is a wheel build, but we use conda packages to get all the requirements. The binary
+requirements (png, freetype,...) are statically linked and therefore not needed during the wheel
+install.
+
+The commands below assume that you can compile a native python lib for the python version of your
+choice. See [this howto](http://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/)
+how to install and setup such environments. If in doubt: use python 3.5 as it mostly works
+without fiddling with environment variables.
+
+``` sh
+# create a new environment with the required packages
+conda create  -n "matplotlib_build" python=3.4 numpy python-dateutil pyparsing pytz tornado pyqt cycler tk libpng zlib freetype
+activate matplotlib_build
+# this package is only available in the conda-forge channel
+conda install -c conda-forge msinttypes
+# for python 2.7
+conda install -c conda-forge functools32
+
+# copy the libs which have "wrong" names
+set LIBRARY_LIB=%CONDA_DEFAULT_ENV%\Library\lib
+mkdir lib || cmd /c "exit /b 0"
+copy %LIBRARY_LIB%\zlibstatic.lib lib\z.lib
+copy %LIBRARY_LIB%\libpng_static.lib lib\png.lib
+
+# Make the header files and the rest of the static libs available during the build
+# CONDA_DEFAULT_ENV is a env variable which is set to the currently active environment path
+set MPLBASEDIRLIST=%CONDA_DEFAULT_ENV%\Library\;.
+
+# build the wheel
+python setup.py bdist_wheel
+```
+
+The `build_alllocal.cmd` script automates these steps if you already created and activated the conda environment.
+
+
+## Conda packages
+
+This needs a [working installed C compiler](http://blog.ionelmc.ro/2014/12/21/compiling-python-extensions-on-windows/)
+for the version of python you are compiling the package for but you don't need to setup the
+environment variables.
+
+```sh
+# only the first time...
+conda install conda-build
+
+# the python version you want a package for...
+set CONDA_PY=3.5
+
+# builds the package, using a clean build environment
+conda build ci\conda_recipe
+
+# install the new package
+conda install --use-local matplotlib
+```
