 ## Getting Started
 
 ### Prerequisites
 
 You must have Kubernetes cluster to be up and running to deploy this application in native way.
 
-You also may run it with Docker and possibly Docker Compose, after translating k8s manifests to docker or docker-compose scenario.
-
-See [./deploy](./deploy) folder.
-
 ### Installation
 
-⚠️ Development stage.
-
 At the moment, installation is as simple as:
 
 ```
-kubectl apply -R -f ./deploy
+git clone https://github.com/agrrh/pagetron.git
+
+helm install pagetron \
+  pagetron/deploy/helm/pagetron \
+  --upgrade \
+  --namespace pagetron \
+  --values values.yaml
 ```
 
 This will create some resources in your cluster:

 ## Usage
 
-⚠️ Development stage.
-
-### Setting up monitoring
-
-To monitor your stuff, you must target metrics collector (currently, `blackbox` exporter) to desired resources in `deploy/prometheus/prometheus.configmap.yaml`:
-
-```
-- targets:
-  - https://example.org
-  - https://api.example.org
-```
-
-### Backend
-
-First, expose metrics on your local environment:
-
-```
-kubectl port-forward -n pagetron svc/prometheus 9090:9090
-```
-
-Then run backend API:
-
-```
-cd backend
-
-docker build . -t local/pagetron:backend
-docker run --rm -ti --network host local/pagetron:backend
-```
-
-### Frontend
-
-Just run frontend:
-
-```
-npm i
-npm run dev
-```
-
-Then you may visit UI:
-
-http://localhost:5173/
