+The home for public Helm charts for Ditto.
+
+## Self hosting a Big Peer
+
+Ditto offers a Helm chart for deploying a Big Peer on Kubernetes.
+To install the chart, add the Ditto Helm repository:
+
+```bash
+  helm repo add ditto https://getditto.github.io/helm-charts/
+```
+
+We will then need to install some CRDs that are required for the Big Peer to run:
+
+```bash
+  kubectl apply --server-side --force-conflicts -f https://github.com/cert-manager/cert-manager/releases/download/v1.6.1/cert-manager.crds.yaml
+  kubectl apply --server-side -f https://raw.githubusercontent.com/getditto/helm-charts/main/crds/ditto_v1alpha1_bigpeer_crd.yaml
+  kubectl apply --server-side -f https://raw.githubusercontent.com/getditto/helm-charts/main/crds/ditto_v1alpha1_ditto_crd.yaml
+
+```
+
+Then using  the values file
+[values.yaml](https://github.com/getditto/helm-charts/blob/main/charts/big-peer/values.yaml) 
+which can be modified to suit your needs, install the chart:
+
+```bash
+  helm install ditto-bp ditto/big-peer -f values.yaml
+```
+
