# AMQP Camel K examples
-Find useful examples about how to use AMQP in a Camel K integration.
+These examples demonstrate how to use AMQP in a Camel K integration.
-You may find useful instructions [how to install a JMS/AMQP Broker on
Kubernetes](./artemis/) for demo purposes.
\ No newline at end of file
+You can find more information about Apache Camel and Apache Camel K on the
[official Camel website](https://camel.apache.org).
+
+## Before you begin
+
+Read the general instructions in the [root README.md file](/README.md) for
setting up your environment and the Kubernetes cluster before looking at this
example.
+
+Make sure you've read the [installation
instructions](https://camel.apache.org/camel-k/latest/installation/installation.html)
for your specific
+cluster before starting the example.
+
+## Additional Requirements for running this example
+
+**An AMQP Broker**: needed MoM for running the examples. For installation
instructions, see [how to install a JMS/AMQP Broker on Kubernetes](./artemis/)
for demo purposes.
+
+## Understanding the Example
+
+- [`AmqpConnectionBeanProducer.java`](./AmqpConnectionBeanProducer.java)
defines a route that generates a message every second and sends it to an amqp
queue.
+- [`AmqpConnectionBeanConsumer.java`](./AmqpConnectionBeanConsumer.java)
consumes messages from the amqp queue, logs them to the logger using the info
level
+- [`amqp.groovy`](./amqp.groovy) generates a message every second and sends to
amqp topic
+- [`amqp.properties`](./amqp.properties) holds required credentials to connect
to broker.
+
+## Running the Example
+You should have an amqp broker running in a namespace, if not, see [how to
install a JMS/AMQP Broker on Kubernetes](./artemis/)
+
+To create a secret for your credentials, run:
+```
+kubectl create secret generic my-amqp --from-file=amqp.properties
+```
+
+To run an integration that sends message to amqp queue, run:
+```
+kamel run AmqpConnectionBeanProducer.java --config secret:my-amqp
+```
+
+To consume messages from the amqp queue, run:
+```
+kamel run AmqpConnectionBeanConsumer.java --dev --config secret:my-amqp
+```
+The terminal should show the logged messages:
+```console
+[1] 2022-06-21 15:44:46,513 INFO [info] (Camel (camel-1) thread #1 -
JmsConsumer[example]) Exchange[ExchangePattern: InOnly, BodyType: String, Body:
