 ## 🖖Introduction
 
-This guide will help you install Longhorn on a Kubernetes cluster. Longhorn is a distributed block storage system for Kubernetes. It is built using containers and microservices. Longhorn creates a dedicated storage controller for each block device volume and synchronously replicates the volume across multiple replicas stored on multiple nodes. The storage controller and replicas are themselves orchestrated using Kubernetes. Longhorn is lightweight, reliable, and easy to use.
+This document provides a step-by-step guide to installing `Longhorn` on the servers (nodes) in the supercluster. The steps outlined in this document are essential for ensuring the proper functioning of the servers (nodes) and the supercluster.
 
 ## ✨Steps

+### 👉Step 1: Test if the system is ready for Longhorn
 
-- Update and upgrade the system.
-```bash
-sudo apt-get update && sudo apt-get upgrade -y

 ```
 
-- Create a secret.
+### 👉Step 7: Create a secret
+
 ```bash
 kubectl create secret generic basic-auth -n longhorn-system --from-file=auth
 rm auth
 # kubectl delete secret basic-auth -n longhorn-system

 # Namespace: longhorn-system
 # Port: 8080
 ```
 
-- Access the Longhorn UI.
-```bash
-kubectl get ingress -A

+### 👉Step 9: Access the Longhorn UI
 
-- Test the Longhorn UI.
 ```bash
-curl http://<EXTERNAL_IP> # <EXTERNAL_IP> is the IP address of the ingress controller
+kubectl get ingress -A
 ```
