+# Netflux on Kubernetes
+
+## Installation
+
+### cert-manager
+
+cert-manager should only be installed in production. It cannot be installed as a subchart.
+
+See: https://cert-manager.io/docs/installation/helm/
+
+```
+helm repo add jetstack https://charts.jetstack.io
+helm repo up
+helm install cert-manager jetstack/cert-manager --namespace cert-manager --create-namespace --version v1.8.0 --set installCRDs=true
+
+# create issuers
+kubectl apply -f cert-manager/issuer-staging.yml
+kubectl apply -f cert-manager/issuer-production.yml
+```
+
+This should be sufficient for cert-manager to issue certificates automatically when the
+`tls.enabled` value is set to `true`.
