    In this example, executing the command generates unit tests for the `add` function and the `Calculator` class defined in `example.py`. The tests verify whether the `add` function correctly computes the sum of two numbers and if the `Calculator`'s `subtract` method accurately performs subtraction.

+
+**Example**
+
+Consider a Python file named ``example.py``:
+
+.. code-block:: python
+
+   # example.py
+
+   def add(a, b):
+       """Add two numbers and return the result."""
+       return a + b
+
+   class Calculator:
+       """A simple calculator class."""
+
+       def subtract(self, a, b):
+           """Subtract b from a and return the result."""
+           return a - b
+
+To generate documentation for ``example.py``, execute the following command:
+
+.. code-block:: shell
+
+   $ codergpt document example.py
+
+This command will produce documentation files that include explanations for all functions and classes within the ``example.py`` file. By default, the output file will be named after the input file with an ``.rst`` extension and saved in the directory specified by ``DOCS_DIR``. If an ``<outfile>`` is provided, the documentation will be written to that file instead.
+
+The content of the generated documentation files will vary based on the implementation of the ``CodeDocumenter.document`` method but would typically resemble the following structured documentation:
+
+.. code-block:: rst
+
+   add Function
+   ------------
+
+   .. autofunction:: example.add
+
+   Calculator Class
+   ----------------
+
+   .. autoclass:: example.Calculator
+      :members:
+
+In this case, running the command produces ReStructuredText (RST) formatted documentation for the entire ``example.py`` file. The documentation includes detailed descriptions of the `add` function and the `Calculator` class, as well as any public methods of the class.
