-## Prerequisite
-Any kubernetes Cluster
+## Requirements
+- [Go Programming language](https://go.dev/)
+- [Docker](https://www.docker.com/) 
+- [Kubernetes Cluster](https://kubernetes.io/)
+- [Helm v3](https://helm.sh/)
 
 ## Setup Guide
-We have documented some of the most popular and easiest ways of creating local kubernetes clusters and setting up the development environment for devtron in our machine.
 
-* [Over Minikube Cluster](https://dev.to/arushi09/local-kubernetes-development-made-easy-with-minikube-devtron-17hf)
-* [Over k3s Cluster using k3d](https://hackernoon.com/how-to-install-k3d-and-devtron-locally-for-local-kubernetes-development)
+### Install Devtron in a Kubernetes cluster
+
+1. [Create a Kubernetes Cluster](https://docs.devtron.ai/getting-started#create-a-kubernetes-cluster)
+   - 2 vCPUs
+   - 4GB+ of free memory
+   - 20GB+ free disk space
+
+2. [Install Devtron with CI/CD along with GitOps (Argo CD) - Full mode](https://docs.devtron.ai/install/install-devtron-with-cicd-with-gitops)
+
+    ```bash
+    helm repo add devtron https://helm.devtron.ai
+    helm repo update devtron
+    helm install devtron devtron/devtron-operator \
+      --create-namespace --namespace devtroncd \
+      --set installer.modules={cicd} \
+      --set argo-cd.enabled=true
+    ```
+
+    Note: If you want to install Devtron on a Managed Kubernetes cluster, please [refer to the guide](https://docs.devtron.ai/install/demo-tutorials).
+
+3. Download the kubeconfig file to access your cluster. It’s a good idea to set it up locally and configure the context to point to the specific cluster you’re working with.
+
+4. Forward the port of PostgreSQL service and Devtron NATS service:
+
+    ```bash
+    kubectl -n devtroncd port-forward svc/devtron-nats 4222:4222 
+    kubectl -n devtroncd port-forward svc/postgresql-postgresql 5432:5432
+    ```
+
+5. Use this command to extract the password of PostgreSQL (Required to put in ENV):
+
+    ```bash
+    kubectl exec -it -n devtroncd postgresql-postgresql-0 -- printenv | grep POSTGRES_PASSWORD
+    ```
+
+### Prepare Your Local Workspace
+
+Navigate to the `github.com` directory on your local machine:
+
+- `cd go/src/github.com`
+- `git clone http://github.com/devtron-labs/devtron`
+- Configure [Environment Variables](https://github.com/devtron-labs/devtron/blob/main/scripts/dev-conf/envfile.env)
+- Run the server:
+
+    ```bash
+    make run
+    ```
+
+This will start your server on `localhost:8080`.
