 # RabbitMQ Messaging Topology Kubernetes Operator
 
-Kubernetes operator to manage [RabbitMQ](https://www.rabbitmq.com/) messaging topologies within a RabbitMQ cluster deployed via the [RabbitMQ Cluster Kubernetes Operator](https://github.com/rabbitmq/cluster-operator/). This repository contains a [custom controller](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/#custom-controllers) and [custom resource definitions (CRDs)](https://kubernetes.io/docs/concepts/extend-kubernetes/api-extension/custom-resources/#customresourcedefinitions) enabling a declarative API for RabbitMQ messaging topologies.

+## Quickstart
+
+Before deploying Messaging Topology Operator, you need to have:
+
+1. A Running k8s cluster
+2. RabbitMQ [Cluster Operator](https://github.com/rabbitmq/cluster-operator) installed in the k8s cluster
+3. A [RabbitMQ cluster](https://github.com/rabbitmq/cluster-operator/tree/main/docs/examples) deployed using the Cluster Operator
+
+If you have `kubectl` configured to access your running k8s cluster, you can then run the following command to install the Messaging Topology Operator:
+
+```bash
+kubectl apply -f https://github.com/rabbitmq/messaging-topology-operator/releases/download/latest/messaging-topology-operator.yml
+```
+
+You can create RabbitMQ resources:
+
+1. [Queue](./docs/examples/queues)
+2. [Exchange](.docs/examples/exchanges)
+3. [Binding](.docs/examples/bindings)
+4. [User](.docs/examples/users)
