+The main commands are ```install``, ``uninstall``, and ``lock``, which generates a ``Pipfile.lock``. These are intended to replace ``$ pip install`` usage, as well as manual virtualenv management.
+
+Basic Concepts
+//////////////
+
+- When no parameters are passed to ``install``, a virtualenv will be created if it doesn't exist, and all packages specified will be installed.
+- When no parameters are passed to ``uninstall``, all packages will be uninstalled.
+
+Other Commands
+//////////////
 
 - ``shell`` will spawn a shell with the virtualenv activated.
 - ``python`` will run the Python interpreter from the virtualenv, with any arguments forwarded.
 - ``where`` will give location information about the current project.
 - ``check`` asserts that PEP 508 requirements are being met by the current environment.
