+### Creating a Memphis function
+Utility for creating Memphis functions.
+event_handler gets the message payload as bytes and message headers as a dict and should return the modified payload and headers.<br>
+An exception should be raised if the message should be considered failed and go into the dead-letter station.<br>
+if all returned values are None the message will be filtered out from the station.
+
+> Make sure to encode the bytes object that you will return with utf-8!
+
+```python
+import json
+import base64
+from memphis.functions import create_function
+
+def handler(event, context): # this function name should be passed to the memphis.yaml file in the handler section
+    return create_function(event, user_func = event_handler)
+
+def event_handler(msg_payload, msg_headers):
+  try:
+    payload =  str(msg_payload, 'utf-8')
+    as_json = json.loads(payload)
+    as_json['modified'] = True
+
+    return bytes(json.dumps(as_json), encoding='utf-8'), msg_headers
+  except Exception as e:
+    raise e
