+# project
+// TODO(user): Add simple overview of use/purpose
+
+## Description
+// TODO(user): An in-depth paragraph about your project and overview of use
+
+## Getting Started
+You’ll need a Kubernetes cluster to run against. You can use [KIND](https://sigs.k8s.io/kind) to get a local cluster for testing, or run against a remote cluster.
+**Note:** Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster `kubectl cluster-info` shows).
+
+### Running on the cluster
+1. Install Instances of Custom Resources:
+
+```sh
+kubectl apply -f config/samples/
+```
+
+2. Build and push your image to the location specified by `IMG`:
+
+```sh
+make docker-build docker-push IMG=<some-registry>/project:tag
+```
+
+3. Deploy the controller to the cluster with the image specified by `IMG`:
+
+```sh
+make deploy IMG=<some-registry>/project:tag
+```
+
+### Uninstall CRDs
+To delete the CRDs from the cluster:
+
+```sh
+make uninstall
+```
+
+### Undeploy controller
+UnDeploy the controller to the cluster:
+
+```sh
+make undeploy
+```
+
+## Contributing
+// TODO(user): Add detailed information on how you would like others to contribute to this project
+
+### How it works
+This project aims to follow the Kubernetes [Operator pattern](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/)
+
+It uses [Controllers](https://kubernetes.io/docs/concepts/architecture/controller/) 
+which provides a reconcile function responsible for synchronizing resources untile the desired state is reached on the cluster 
+
+### Test It Out
+1. Install the CRDs into the cluster:
+
+```sh
+make install
+```
+
+2. Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):
+
+```sh
+make run
+```
+
+**NOTE:** You can also run this in one step by running: `make install run`
+
+### Modifying the API definitions
+If you are editing the API definitions, generate the manifests such as CRs or CRDs using:
+
+```sh
+make manifests
+```
+
+**NOTE:** Run `make --help` for more information on all potential `make` targets
+
