 Building rendered documentation

-Documents can be built into HTML-formatted pages from project root directory by
-running the following command.
+To install Python dependencies using Poetry:
+
+.. code:: shell
+
+    poetry install
+
+Poetry will create a new virtual environment and install all dependencies listed
+in ``pyproject.toml``. You can get information about this environment, such as
+its location and the Python version, with the command:
+
+.. code:: shell
+
+    poetry env info
+
+If you have already sourced a virtual environment, Poetry will respect this and
+install dependencies there.
+
+Once all dependencies are installed, the documentation can be compiled into
+HTML-formatted pages from the project root directory by running:
 
 .. code:: shell
 
    poetry run make doc

 We also support building documentation in other formats. From the ``docs``
 directory of the project, run the following command to see the supported
-formats. It is important to note that you will not get the correct result if

+Building rendered documentation from Poetry's virtual environment
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
 
-   The ``run`` command used above executes ``make`` in the projects virtual
-   environment. To spawn a shell in this environment, use ``poetry
-   shell``. For other use cases, please see the official `Poetry`_
-   documentation.
+The command ``poetry run`` used in the steps above executes the input command
+from inside the project's virtual environment. The easiest way to activate this
+virtual environment is with the ``poetry shell`` command.
+
+Running ``poetry shell`` from the directory containing this project, activates
+the same virtual environment. This creates a sub-shell through which you can
+build the documentation directly with ``make``.
+
+.. code:: shell
+
+    poetry shell
+    make doc
+
+Type ``exit`` to deactivate the virtual environment and exit this new shell. For
+other use cases, please see the official `Poetry`_ documentation.

 creates the documentation. Once done, exit the container and output from the
