 For optimal performance, we recommend using a cloud provider that allows you to provision Kubernetes clusters with fast persistent storage or self hosting your own Kubernetes cluster with fast persistent storage.
 
+### Shadowforking
+In order to enable shadowfork capabilities, you can use the `network_params.network` flag. The expected value is the name of the network you want to shadowfork followed by `-shadowfork`. Please note that `persistent` configuration parameter has to be enabled for shadowforks to work! Current limitation on k8s is it is only working on a single node cluster. For example, to shadowfork the Holesky testnet, you can use the following command:
+```yaml
+...
+network_params:
+  network: "holesky-shadowfork"
+persistent: true
+...
+```
+
+##### Shadowforking custom verkle networks
+In order to enable shadowfork capabilities for verkle networks, you need to define electra and mention verkle in the network name after shadowfork.
+```yaml
+...
+network_params:
+  electra_fork_epoch: 1
+  network: "holesky-shadowfork-verkle"
+persistent: true
+...
+```

 #### Taints and tolerations
 It is possible to run the package on a Kubernetes cluster with taints and tolerations. This is done by adding the tolerations to the `tolerations` field in the `network_params.yaml` file. For example:
