-# Relaychain
-## Install relaychain 
-```shell
-helm upgrade --install bootnode  . -f examples/local-rococo/bootnode.yaml
-kubectl wait --for=condition=Ready pod bootnode-0 --timeout=90s
-helm upgrade --install validators  . -f examples/local-rococo/validators-alice-bob.yaml
+## Example Rococo Local Chain
+This example demonstrates deploying a Rococo-local (relaychain) test chain and parachain test chains in Kubernetes. 
+The setup includes deploying one bootnode, two validators, and two parachain nodes via the Helm chart. 
+Once both validators are running you will see block production. 
+A custom chainspec is generated in the initcontainer on the bootnode, which is used to connect all relaychain nodes together.
 
-```
+### Relaychain Setup:
+1. **Install the Relaychain:**
+   Install the Helm charts for the bootnode and validators. Ensure that you have Helm installed and configured with the appropriate Kubernetes cluster.
+   ```shell
+   helm upgrade --install bootnode  . -f examples/local-rococo/bootnode.yaml
+   kubectl wait --for=condition=Ready pod bootnode-0 --timeout=90s
+   helm upgrade --install validators  . -f examples/local-rococo/validators-alice-bob.yaml
+   ```
 
-## Access to relaychain RPC
-```shell
-kubectl port-forward bootnode-0 9944:9944
-```
-open:  https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/explorer
+2. **Access Relaychain RPC:**
+   Port-forward to access the relaychain RPC. This will allow you to interact with the relaychain using Polkadot.js apps or other tools.
+   ```shell
+   kubectl port-forward bootnode-0 9944:9944
+   ```
+   Open Polkadot.js apps at https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/explorer to explore the relaychain.

-# Parachain
-## Install parachain 
-```shell
-helm upgrade --install parachain  . -f examples/local-rococo/asset-hub.yaml
-```
 
-## Onboard parachain
-1. Find the para_id and Genesis state
-```shell
-kubectl logs --tail 10 -f parachain-node-0 dump-state-and-wasm
-# Parachain Id: 
-#  "para_id": 1000,
-# Genesis head:  
-# 0x00000000000000000000000000000000000000000000000000000000000000000061dc4546910e4a874f59af705dd079344ecb7759f526cf86cf21db67473d0b4f03170a2e7597b7b7e3d84c05391d139a62b157e78786d8c082f29dcf4c11131400
-```
-2. Download genesis-wasm
-```shell
-kubectl cp parachain-node-0:/chain-data/genesis-wasm genesis-wasm
-```
-3. On relaychain RPC submit following call:
-https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/sudo
-```shell
-parasSudoWrapper.sudoScheduleParaInitialize(id, genesis)
-id = 1000
-genesisHead = 0x00000000000000000000000000000000000000000000000000000000000000000061dc4546910e4a874f59af705dd079344ecb7759f526cf86cf21db67473d0b4f03170a2e7597b7b7e3d84c05391d139a62b157e78786d8c082f29dcf4c11131400
-validationCode = file upload(genesis-wasm)
-paraKind = Yes
-```

+### Parachain Setup:
+1. **Install the Parachain:**
+   Install the Helm chart for the parachain. This will deploy the parachain nodes onto your Kubernetes cluster.
+   ```shell
+   helm upgrade --install parachain  . -f examples/local-rococo/parachain.yaml
+   ```
 
-## Access to parachain RPC
+2. **Onboard the Parachain:**
+   - **Find Para_id and Genesis State:**
+     Obtain the Para_id and genesisHead by checking the logs of the parachain node.
+     ```shell
+     kubectl logs --tail 10 -f parachain-node-0 dump-state-and-wasm
+     # Parachain Id: 
+     #  "para_id": 1000,
+     # Genesis head:  
+     # 0x00000000000000000000000000000000000000000000000000000000000000000061dc4546910e4a874f59af705dd079344ecb7759f526cf86cf21db67473d0b4f03170a2e7597b7b7e3d84c05391d139a62b157e78786d8c082f29dcf4c11131400
+     ```
+   - **Download Genesis-Wasm:**
+     Copy the genesis-wasm file from the parachain node to your local machine.
+     ```shell
+     kubectl cp parachain-node-0:/chain-data/genesis-wasm genesis-wasm
+     ```
+   - **Submit a Call to Relaychain RPC:**
+     Use [Polkadot.js](https://polkadot.js.org/apps/?rpc=ws%3A%2F%2F127.0.0.1%3A9944#/sudo) apps to submit a call to the relaychain RPC for onboarding the parachain.

-## Cleanup
+
+### Cleanup:
+Delete the Helm releases for bootnode, validators, and parachain. Optionally, clean up PVCs if necessary.

+# Clean PVCs if needed
+# kubectl delete pvc --all
+```
