+
+Logging in a ``junifer`` extension
+==================================
+
+It is important to have proper logging in your code and ``junifer`` makes it trivial to do so for your extensions.
+
+For DataGrabber:
+
+.. code-block:: python
+
+   from junifer.datagrabber import logger
+
+
+For Preprocessor:
+
+.. code-block:: python
+
+   from junifer.preprocess import logger
+
+
+For Marker:
+
+.. code-block:: python
+
+   from junifer.marker import logger
+
+
+For Storage:
+
+.. code-block:: python
+
+   from junifer.storage import logger
+
+
+Importing the correct logger will give you a properly set up logger which will fit right in with the rest of ``junifer``\'s log output.
