+## Installing the Chart
+
+To install the chart with the release name `my-release`:
+
+```bash
+$ helm install my-release ckotzbauer/vulnerability-operator
+```
+
+The command deploys the vulnerability-operator to the Kubernetes cluster using the default configuration. The [configuration](#configuration) section lists the parameters that can be configured during installation.
+
+## Uninstalling the Chart
+
+To uninstall/delete the `my-release` deployment:
+
+```bash
+$ helm delete my-release
+```
+The command removes all the Kubernetes components associated with the chart and deletes the release.
+
+## Configuration
+
+The following table lists the configurable parameters of the vulnerability-operator chart and their default values.

+Specify each parameter using the `--set key=value[,key=value]` argument to `helm install`. For example,
+
+```bash
+$ helm install my-release \
+    --set key_1=value_1,key_2=value_2 \
+    ckotzbauer/vulnerability-operator
+```
+
+Alternatively, a YAML file that specifies the values for the parameters can be provided while installing the chart. For example,
+
+```bash
+# example for staging
+$ helm install my-release -f values.yaml ckotzbauer/vulnerability-operator
+```
+
+> **Tip**: You can use the default [values.yaml](values.yaml)
