+Previewing your changes
+------------------------
+
+To preview your changes, you can build the documentation locally.
+
+To do this, navigate to the ``MapReader/docs`` directory and run:
+
+.. code-block:: bash
+
+    make livehtml
+
+This will build the documentation and open a new tab in your browser with the documentation.
+
+.. note::
+    If a new tab does not open automatically, you can navigate to ``http://127.0.0.1:8000`` in your browser to view the live documentation.
+
+The ``livehtml`` command will automatically update the documentation as you make changes to the files.
+
