 ## Virtualenv setup
 
-First, you need `pip` and `virtualenv` in your system Python install:
-
-    $ sudo easy_install pip
-    $ sudo pip install virtualenv
-
-Then, in dupeGuru's source folder, create a virtual environment and activate it:
-
-    $ virtualenv --system-site-packages env
-    $ source env/bin/activate
-
-Then, you can install pip requirements in your virtualenv:
-
-    $ pip install -r requirements-[osx|win].txt
-    
-([osx|win] depends, of course, on your platform. On other platforms, just use requirements.txt).
-
-## Alternative: pyvenv
-
-If you're on Python 3.3+, you can use the built-in `pyvenv` instead of `virtualenv`. `pyvenv` is
-pretty much the same thing as `virtualenv`, except that it doesn't install setuptools and pip, so it
-has to be installed manually:
+Use the built-in `pyvenv` to setup a virtual environment, and then install `pip` and run the
+requirements in it:
 
     $ pyvenv --system-site-packages env
     $ source env/bin/activate
