+- ``generator.py`` exposes a class allowing to generate a MISP feed in real time, where each items can be added on daily generated events.
 - ``fromredis.py`` uses ``generator.py`` to generate a MISP feed based on data stored in redis.
 - ``server.py`` is a simple script using *Flask_autoindex* to serve data to MISP.
 - ``MISPItemToRedis.py`` permits to push (in redis) items to be added in MISP by the ``fromredis.py`` script.

+# Utilisation
+
+### Adding items to MISP
+
+```
+# create helper object
+>>> helper = MISPItemToRedis("redis_list_keyname")
+
+# push an attribute to redis
+>>> helper.push_attribute("ip-src", "8.8.8.8", category="Network activity")
+
+# push an object to redis
+>>> helper.push_object({ "name": "cowrie", "session": "session_id", "username": "admin", "password": "admin", "protocol": "telnet" })
+
+# push a sighting to redis
+>>> helper.push_sighting(uuid="5a9e9e26-fe40-4726-8563-5585950d210f")
+```
+
+### Generator
+
+```
+# Create the FeedGenerator object using the configuration provided in the file settings.py
+# It will create daily event in which attributes and object will be added
+generator = FeedGenerator()
+
+# Add an attribute to the daily event
+attr_type = "ip-src"
+attr_value = "8.8.8.8"
+additional_data = {}
+generator.add_attribute_to_event(attr_type, attr_value, **additional_data)
+
+# Add a cowrie object to the daily event
+obj_name = "cowrie"
+obj_data = { "session": "session_id", "username": "admin", "password": "admin", "protocol": "telnet" }
+generator.add_object_to_event(obj_name, **obj_data)
