 # Example RabbitMQ stages
-This example builds upon the `examples/developer_guide/2_2_rabbitmq` example adding a C++ implementation for the `RabbitMQSourceStage`.
+This example builds upon the `examples/developer_guide/2_2_rabbitmq` example adding a C++ implementation for the `RabbitMQSourceStage` along with adding package install scripts.
 
 This example adds two flags to the `read_simple.py` script. A `--use_cpp` flag which defaults to `True` and a `--num_threads` flag which defaults to the number of cores on the system as returned by `os.cpu_count()`.
 
+## Building the Example
+There are two ways to build the example. The first is to build the example along with Morpheus by passing the `-DMORPHEUS_BUILD_EXAMPLES=ON` flag to cmake, for users using the `scripts/compile.sh` at the root of the Morpheus repo can do this by setting the `CMAKE_CONFIGURE_EXTRA_ARGS` environment variable:
+```bash
+CMAKE_CONFIGURE_EXTRA_ARGS="-DMORPHEUS_BUILD_EXAMPLES=ON" ./scripts/compile.sh
+```
+
+The second is to build the example as a standalone project. From the root of the Morpheus repo execute:
+```bash
+cd examples/developer_guide/4_rabbitmq_cpp_stage
+./compile.sh
+
+# Optionally install the package into the current python environment
+pip install ./
+```
+
+
 ## Testing with a RabbitMQ container
 Testing can be performed locally with the RabbitMQ supplied docker image from the [RabbitMQ container registry](https://registry.hub.docker.com/_/rabbitmq/):
 ```bash
