+## Logging
+You should define a logger in your app in order to make sure you get all the messages from the different components.<br>
+It will help you debug, and make sure you don't miss issues when they occur.<br>
+The simplest way to define a logger, if you have no experience with the python logger - will be something like this:
+```py
+import logging
+logging.basicConfig(format='%(asctime)s %(message)s', level=logging.INFO)
+```
