+================
+Enable Logging
+================
+
+Telethon makes use of the `logging`__ module, and you can enable it as follows:
+
+    .. code-block:: python
+
+        import logging
+        logging.basicConfig(level=logging.DEBUG)
+
+You can also use it in your own project very easily:
+
+    .. code-block:: python
+
+        import logging
+        logger = logging.getLogger(__name__)
+
+        logger.debug('Debug messages')
+        logger.info('Useful information')
+        logger.warning('This is a warning!')
