+
+Install `pip`. On many systems, this can be achieved with the command `python
+-m ensurepip`. If this is not possible, use your system's package manager to
+install the `python-pip` package.
+
+Next, install `virtualenv` using the following command:
+
+```bash
+pip install virtualenv
+```

 To get the tests running, you need to set up the test domains in your
 [`hosts` file](http://en.wikipedia.org/wiki/Hosts_%28file%29%23Location_in_the_file_system).
