+Disable the speedups Module
+~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+By default Jinja2 will try to compile the speedups module.  This of course
+will fail if you don't have the Python headers or a working compiler.  This
+is often the case if you are installing Jinja2 from a windows machine.
+
+You can disable the speedups extension when installing using the
+``--without-speedups`` flag::
+
+    sudo python setup.py install --without-speedups
+
+You can also pass this parameter to `easy_install` or `pip`.
