 Working on ``cryptography`` requires the installation of a small number of
 development dependencies in addition to the dependencies for
 :doc:`/installation`. These are listed in ``dev-requirements.txt`` and they can
-be installed in a `virtualenv`_ using `pip`_. Once you've installed the
-dependencies, install ``cryptography`` in ``editable`` mode. For example:
+be installed in a `virtualenv`_ using `pip`_. Before you install them, follow
+the **build** instructions in :doc:`/installation` (be sure to stop before
+actually installing ``cryptography``). Once you've done that, install the
+development dependencies, and then install ``cryptography`` in ``editable``
+mode. For example:
 
 .. code-block:: console
 
     $ # Create a virtualenv and activate it
+    $ # Set up your cryptography build environment
     $ pip install --requirement dev-requirements.txt
     $ pip install --editable .
 
 You will also need to install ``enchant`` using your system's package manager
 to check spelling in the documentation.
 
+.. note::
+    There is an upstream bug in ``enchant`` that prevents its installation on
+    Windows with 64-bit Python. See `this Github issue`_ for more information.
+    The easiest workaround is to use 32-bit Python for ``cryptography``
+    development, even on 64-bit Windows.

 You are now ready to run the tests and build the documentation.
