+### Creating a connection
+
+A connection to the RabbitMQ AMQP 1.0 server can be established using the Connection object.
+
+For example:
+
+```python
+    connection = Connection("amqp://guest:guest@localhost:5672/")
+    connection.dial()
+```
+
+### Managing resources
+
+Once we have a Connection object we can get a Management object in order to submit to the server management operations
+(es: declare/delete queues and exchanges, purging queues, binding/unbinding objects ecc...)
+
+For example (this code is declaring an exchange and a queue:
+
+```python
+    management = connection.management()
+
+    print("declaring exchange and queue")
+    management.declare_exchange(ExchangeSpecification(name=exchange_name, arguments={}))
+
+    management.declare_queue(
+        QuorumQueueSpecification(name=queue_name)
+    )
+```
+
+### Publishing messages
+
+Once we have a Connection object we can get a Publisher object in order to send messages to the server (to an exchange or queue)
+
+For example:
+
+```python
+    addr_queue = AddressHelper.queue_address(queue_name)
+    publisher = connection.publisher(addr)
+
+    # publish messages
+    for i in range(messages_to_publish):
+        publisher.publish(Message(body="test"))
+
+    publisher.close()
+```
+
+### Consuming messages
+
+Once we have a Connection object we can get a Consumer object in order to consumer messages from the server (queue).
+
+Messages are received through a callback
+
+For example:
+
+Create a class which extends AMQPMessagingHandler which defines at minimum the on_consumer method, that will receive the 
+messages consumed:
+
+```python
+class MyMessageHandler(AMQPMessagingHandler):
+
+    def __init__(self):
+        super().__init__()
+        self._count = 0
+
+    def on_message(self, event: Event):
+        print("received message: " + str(event.message.body))
+
+        # accepting
+        self.delivery_context.accept(event)
+```
+
+Then from connection get a consumer object:
+
+```python
+    addr_queue = AddressHelper.queue_address(queue_name)
+    consumer = connection.consumer(addr_queue, handler=MyMessageHandler())
+
+    try:
+        consumer.run()
+    except KeyboardInterrupt:
+        pass
+```
+
+The consumer will run indifinitively waiting for messages to arrive.
