 ## Example
 With the KWasm Operator it is possile to have a more fine grained controll on the node provisioning. In this example we create a KinD cluster with three nodes and install the KWasm Operator. A single node will be provisioned and a wasm pod will be scheduled on exactly that node. 
-```
+```bash
+# Create cluster
 kind create cluster --config examples/kind/cluster.yaml
-make install run
+# Add helm repo
+helm repo add kwasm http://kwasm.sh/kwasm-operator/
+# Install operator

+description: A Helm chart for Kubernetes
+
+# A chart can be either an 'application' or a 'library' chart.
+#
+# Application charts are a collection of templates that can be packaged into versioned archives
+# to be deployed.
+#
+# Library charts provide useful utilities or functions for the chart developer. They're included as
+# a dependency of application charts to inject those utilities and functions into the rendering
+# pipeline. Library charts do not define any templates and therefore cannot be deployed.
+type: application
+
+# This is the chart version. This version number should be incremented each time you make changes
+# to the chart and its templates, including the app version.
+# Versions are expected to follow Semantic Versioning (https://semver.org/)
+version: 0.1.0

+# This is the version number of the application being deployed. This version number should be
+# incremented each time you make changes to the application. Versions are not expected to
+# follow Semantic Versioning. They should reflect the version the application is using.
+# It is recommended to use it with quotes.
