+## Getting Started
+
+### Prerequisites
+
+- go version v1.23.0+
+- docker version 17.03+.
+- kubectl version v1.11.3+.
+- Access to a Kubernetes v1.11.3+ cluster.
+
+### To Deploy on the cluster
+
+**Build and push your image to the location specified by `IMG`:**
+
+```sh
+make docker-build docker-push IMG=<some-registry>/operator:tag
+```
+
+**NOTE:** This image ought to be published in the personal registry you specified.
+And it is required to have access to pull the image from the working environment.
+Make sure you have the proper permission to the registry if the above commands don't work.
+
+**Install the CRDs into the cluster:**
+
+```sh
+make install
+```
+
+**Deploy the Manager to the cluster with the image specified by `IMG`:**
+
+```sh
+make deploy IMG=<some-registry>/operator:tag
+```
+
+> **NOTE**: If you encounter RBAC errors, you may need to grant yourself cluster-admin
+> privileges or be logged in as admin.
+
+**Create instances of your solution**
+You can apply the samples (examples) from the config/sample:
+
+```sh
+kubectl apply -k config/samples/
+```
+
+> **NOTE**: Ensure that the samples has default values to test it out.
+
+### To Uninstall
+
+**Delete the instances (CRs) from the cluster:**
+
+```sh
+kubectl delete -k config/samples/
+```
+
+**Delete the APIs(CRDs) from the cluster:**
+
+```sh
+make uninstall
+```
+
+**UnDeploy the controller from the cluster:**
+
+```sh
+make undeploy
+```
+
+## Project Distribution
+
+Following the options to release and provide this solution to the users.
+
+### By providing a bundle with all YAML files
+
+1. Build the installer for the image built and published in the registry:
+
+    ```sh
+    make build-installer IMG=<some-registry>/operator:tag
+    ```
+
+   **NOTE:** The makefile target mentioned above generates an 'install.yaml'
+   file in the dist directory. This file contains all the resources built
+   with Kustomize, which are necessary to install this project without its
+   dependencies.
+
+2. Using the installer
+
+   Users can just run 'kubectl apply -f <URL for YAML BUNDLE>' to install
+   the project, i.e.:
+
+    ```sh
+    kubectl apply -f https://raw.githubusercontent.com/<org>/operator/<tag or branch>/dist/install.yaml
+    ```
+
+### By providing a Helm Chart
+
+1. Build the chart using the optional helm plugin
+
+    ```sh
+    kubebuilder edit --plugins=helm/v1-alpha
+    ```
+
+2. See that a chart was generated under 'dist/chart', and users
+   can obtain this solution from there.
+
+**NOTE:** If you change the project, you need to update the Helm Chart
+using the same command above to sync the latest changes. Furthermore,
+if you create webhooks, you need to use the above command with
+the '--force' flag and manually ensure that any custom configuration
+previously added to 'dist/chart/values.yaml' or 'dist/chart/manager/manager.yaml'
+is manually re-applied afterwards.
+
+**NOTE:** Run `make help` for more information on all potential `make` targets
+
+More information can be found via the [Kubebuilder Documentation](https://book.kubebuilder.io/introduction.html)
