+# Perforator Helm Chart
+In this tutorial we will deploy Perforator on a Kubernetes cluster via the Helm package manager without additional database setup.
+
+{% note warning %}
+
+This setup is intended solely for demonstration.
+There is no guarantee for compatibility with older versions of the chart.
+Please do not use it in production environments.
+
+{% endnote %}
+
+## Prerequisites
+
+- Kubernetes cluster
+- Helm 3+
+
+## Adding Helm Repository
+
+```
+helm repo add perforator https://helm.perforator.tech
+helm repo update
+```
+
+## Installing Helm Chart
+
+Create file `my-values.yaml` with values:
+
+my-values.yaml example
+```yaml
+databases:
+  postgresql:
+    migrations:
+      enabled: true
+    db: "perforator"
+    user: "perforator"
+    password: "perforator"
+  clickhouse:
+    migrations:
+      enabled: true
+    insecure: true
+    db: "perforator"
+    user: "perforator"
+    password: "perforator"
+  s3:
+    buckets:
+      profiles: "perforator-profile"
+      binaries: "perforator-binary"
+      taskResults: "perforator-task-results"
+      binariesGSYM: "perforator-binary-gsym"
+    insecure: true
+    force_path_style: true
+    accessKey: "perforator"
+    secretKey: "perforator"
+
+proxy:
+  url_prefix: "http://localhost:8080/static/results/"
+
+testing:
+  enableTestingDatabases: true
+```
+
+Use created values to install chart:
+
+```console
+helm install perforator-release -n perforator perforator/perforator -f my-values.yaml --create-namespace
+```
+
+## Connecting to Perforator UI
+
+To access the Perforator UI, configure port forwarding to the local machine:
+
+```console
+kubectl port-forward svc/perforator-release-perforator-web-service -n perforator 8080:80
+```
+Then open `http://localhost:8080` in your browser
+
+## Uninstalling Helm Chart
+
+```console
+helm uninstall perforator-release -n perforator
+```
