## Description

// TODO(user): An in-depth paragraph about your project and overview of use

67+
## Getting Started
68+
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.
69+
**Note:** Your controller will automatically use the current context in your kubeconfig file (i.e. whatever cluster ` + "`kubectl cluster-info`" + ` shows).
70+
71+
### Running on the cluster
72+
1. Install Instances of Custom Resources:
73+
74+
%s
75+
76+
2. Build and push your image to the location specified by ` + "`IMG`" + `:
77+
78+
%s
79+
80+
3. Deploy the controller to the cluster with the image specified by ` + "`IMG`" + `:
81+
82+
%s
83+
84+
### Uninstall CRDs
85+
To delete the CRDs from the cluster:
86+
87+
%s
88+
89+
### Undeploy controller
90+
UnDeploy the controller to the cluster:
91+
92+
%s
93+
94+
## Contributing
95+
// TODO(user): Add detailed information on how you would like others to contribute to this project
96+
97+
### How it works
98+
This project aims to follow the Kubernetes [Operator pattern](https://kubernetes.io/docs/concepts/extend-kubernetes/operator/)
99+
100+
It uses [Controllers](https://kubernetes.io/docs/concepts/architecture/controller/)
101+
which provides a reconcile function responsible for synchronizing resources untile the desired state is reached on the cluster
102+
103+
### Test It Out
104+
1. Install the CRDs into the cluster:
105+
106+
%s
107+
108+
2. Run your controller (this will run in the foreground, so switch to a new terminal if you want to leave it running):
109+
110+
%s
111+
112+
**NOTE:** You can also run this in one step by running: ` + "`make install run`" + `
113+
114+
### Modifying the API definitions
115+
If you are editing the API definitions, generate the manifests such as CRs or CRDs using:
116+
117+
%s
118+
119+
**NOTE:** Run ` + "`make --help`" + ` for more information on all potential ` + "`make`" + ` targets
120+
