+## Prerequisites
+
+Before using this Helm chart, you should have the following prerequisites:
+
+- Access to Kubernetes cluster (If needed contact your friendly neighbourhood DevOps engineer)
+- Helm >= v3.14.3
+- (**Optional**) helmfile >= v0.162.0 to install this chart
+
+## Installation
+
+> Note: **examples** can be found in the repository
+
+To install this Helm chart, the easiest is to create a helmfile.yaml with needed values and run:
+
+```
+helmfile template
+helmfile apply
+```
+
+Or use helmfile only to generate resources and apply them with kubectl like so:
+
+```
+helmfile template | kubectl -f -
+```
+
+Verify that the chart is deployed successfully:
+
+> Note: `kubectl` is a better suited tool for this
+
+```
+helmfile status
+```
