 ## Requirements
 
+Kubernetes 1.28+
+
 ### Standalone Installation
 
-Node:
+Single Node:
 * 8 vCPUs
 * 8 GB RAM
 
 # Installation
 
+## Download Files
+
+```shell
+git clone https://github.com/OktopUSP/oktopus
+export DEPLOYMENT_PATH=oktopus/deploy/kubernetes
+```
+
 
 ## MongoBD
 
+```shell
+# Mongo DB Operator at mongodb namespace
+helm repo add mongodb https://mongodb.github.io/helm-charts
+
+helm install community-operator mongodb/community-operator --namespace mongodb --create-namespace
+
+# Mongo DB ReplicaSet
+export DEPLOYMENT_PATH=oktopus/deploy/kubernetes
+
+kubectl apply -f $DEPLOYMENT_PATH/mongodb.yaml -n mongodb
+
+# Check Installation
+kubectl get pods -n mongodb
+```
+
+## NATS Server
+
+```shell
+# Download the NATS charts
+helm repo add nats https://nats-io.github.io/k8s/helm/charts/
+
+# Install NATS with Jetstream Enabled
+helm install nats nats/nats --set config.jetstream.enabled=true
+```

+
+
+<b>Node Ports</b>
+
+For this deployment, we are not using a load balancer and kubernetes is deployed on-premises so we are using Nodeports to insource the client traffic into cluster. below the ports set on deployment files:
+
+1. MQTT broker service (mqtt-svc): 30000
+2. Frontend (frontend-svc): 30001
+3. SocketIO: (socketio-svc): 30002
+4. Controller (controller-svc): 30003
+5. WebSocket (ws-svc): 30005
+
+Before deploying the files, edit the frontend.yaml file to set the correct enviroment variables:
+
+```yaml
+env:
+    - name: NEXT_PUBLIC_REST_ENDPOINT
+        value: "<FRONTEND_IP>:30003"
+    - name: NEXT_PUBLIC_WS_ENDPOINT
+        value: "<FRONTEND_IP>:30005"
+``` 
+
+```shell
+kubectl apply -f $DEPLOYMENT_PATH/mqtt.yaml
+kubectl apply -f $DEPLOYMENT_PATH/mqtt-adapter.yaml
+kubectl apply -f $DEPLOYMENT_PATH/adapter.yaml
+kubectl apply -f $DEPLOYMENT_PATH/controller.yaml
+kubectl apply -f $DEPLOYMENT_PATH/socketio.yaml
+kubectl apply -f $DEPLOYMENT_PATH/frontend.yaml
+kubectl apply -f $DEPLOYMENT_PATH/ws.yaml
+kubectl apply -f $DEPLOYMENT_PATH/ws-adapter.yaml
+```
+
+### Checking cluster status:
+
+```shell
+
+kubectl get pods
+kubectl get svc
+
+```
