+# Single-Command Installation Guide
+
+This document provides comprehensive instructions for the quick, single-command installation of the EDA Server Operator. Also covered are additional details such as prerequisites, uninstallation, and troubleshooting tips.
+
+## Prerequisites
+Before proceeding with the installation, ensure that the following prerequisites are met:
+
+1. **Kubernetes Cluster**: You need an active Kubernetes cluster. If you do not have one, you can set it up using platforms like Minikube, Kind, or a cloud provider like AWS, Azure, or GCP.
+
+2. **kubectl**: The Kubernetes command-line tool, kubectl, should be installed and configured to communicate with your cluster. You can check its availability by running `kubectl version`.
+
+## Installation
+The EDA Server Operator can be installed using a single command. This command applies a YAML file from the EDA Server Operator's GitHub repository directly to your Kubernetes cluster.
+
+Run the following command in your terminal to install the latest operator
+
+```bash
+kubectl apply -f https://github.com/ansible/eda-server-operator/releases/latest/download/operator.yaml
+```
+
+If you want to install a specific version instead, modify the version to whichever version you want to install. For example:
+
+```bash
+kubectl apply -f https://github.com/ansible/eda-server-operator/releases/download/1.0.0/operator.yaml
+```
+
+> [!Note]
+> This will create the EDA Server Operator resources in the eda-server-operator-system namespace.
+
+Now create your EDA custom resource by applying the `eda-demo.yml` file and you will soon have a working EDA instance!
+
+```yaml
+# eda-demo.yaml
+apiVersion: eda.ansible.com/v1alpha1
+kind: EDA
+metadata:
+  name: my-eda
+spec:
+  automation_server_url: https://awx-host
+```
+
+```bash
+kubectl apply -f eda-demo.yaml
+```
+
+See the [README.md](../README.md) for more information on configuring EDA by modifying the `spec`.
+
+## Upgrading
+
+## Pre-Upgrade Checklist
+
+* **Backup**: Backup your EDA instance by creating an EDABackup. 
+* **Review Release Notes**: Check the release notes for the new version of the EDA Server Operator. This can be found on the GitHub [releases page](https://github.com/ansible/eda-server-operator/releases). Pay attention to any breaking changes, new features, or specific instructions for upgrading from your current version.
+
+### Upgrade the Operator
+
+Check the [Releases Page](https://github.com/ansible/eda-server-operator/releases) for the latest EDA Server Operator verion. Copy the URL to the `operator.yaml` artifact for it, then apply it.
+
+For example, if upgrading to version 1.1.0, the command would be:
+
+```bash
+kubectl apply -f https://github.com/ansible/eda-server-operator/releases/download/1.1.0/operator.yaml
+``````
+
+Monitor the upgrade process by checking the status of the pods in the eda-server-operator-system namespace. You can use the following command:
+
+```bash
+kubectl get pods -n eda-server-operator-system
+```
+
+
+## Cleanup
+If you wish to remove the EDA Server Operator from your Kubernetes cluster, follow these steps:
+
+Run the following command:
+
+```bash
+kubectl delete -f https://github.com/ansible/eda-server-operator/releases/download/1.0.0/operator.yaml
+```
