+You can also do this configuration by editing your ``pip.conf`` or ``pip.ini``

+If you don't have a ``pip.conf`` or ``pip.ini`` file at these locations, you can

+If you already have a configuration file, just add the following line under the
+``[global]`` settings to require an active virtual environment:

 use across different projects consistenly) and this can be accomplished by adding
