+.. tip::
+   If you prefer, or are already using virtualenv_ in your workflow, you can
+   install ``build`` with the optional ``virtualenv`` depedency:
+
+   .. code-block:: sh
+
+      $ pip install 'build[virtualenv]'
+
+   this way, ``build`` will use virtualenv_ for isolation, instead of venv_.
+   This can be particularly useful, for example, when using automation tools
+   that rely on virtualenv_, such as tox_, or when your operating system's
+   Python package does not include venv_ in the standard installation (such as
+   some versions of Ubuntu).
