+# Nightfall Client Playbook — Plume Testnet
+
+## 1) Get the source
+
+```bash
+git clone https://github.com/EYBlockchain/nightfall_4_CE.git
+cd nightfall_4_CE
+git checkout plume_testnet_client
+```
+
+Make sure you pulled the latest changes.
+
+---
+
+## 2) Stop & clean previous Docker state
+
+```bash
+# DANGER: removes commitment db
+docker compose --profile indie-client down -v
+# DANGER: removes images, containers, networks, and volumes
+docker system prune -a --volumes
+```
+
+---
+
+## 3) Wallet setup: MetaMask + Plume testnet
+
+1. Install the MetaMask browser extension: [https://metamask.io/en-GB](https://metamask.io/en-GB)
+2. Create a **new network** in MetaMask for **Plume testnet** using the parameters published here: [https://thirdweb.com/plume-testnet](https://thirdweb.com/plume-testnet)
+3. Import or create an account and ensure it has **≥ 10 PLUME** for fees (test funds).
+
+---
+
+## 4) Create `local.env`
+
+Create a file named `local.env` in the repo root with the following content. Replace placeholders (`0x....`) with your values where indicated.
+
+```bash

+If you host a online webhook, please put you url in `WEBHOOK_URL`, if you want to host a local webhook, you can follow nf_4.md about how to host a local webhook and replace the webhook url. For easier start, run `python3 webhook.py` in seperate terminal to start a testing local webhook. Webhook is essential to de-escrow fund back to host chain.
+Please remove all comments (beginning with `#`) in your local.env file.

+
+## 5) Build and run the Nightfall client
+
+From the repo root:
+
+```bash
+docker compose --profile indie-client build
+
+docker compose --profile indie-client --env-file local.env up
+```
+
+## 6) Deployment script
+
+You can also deploy your own ERC-20/721/1155/3525 contracts using the following script: `blockchain_assets/script/mock_deployment.s.sol`
+
+Or, you can use mock ERC deployments to play with.
+
+1.	`forge build` 
+2.	`export $(grep -v '^#' local.env | xargs)`  
+3.  `forge script blockchain_assets/script/mock_deployment.s.sol:MockDeployer --rpc-url https://testnet-rpc.plume.org --broadcast --legacy --slow`	
+
+
+You can then interact with those contract using the APIs: https://github.com/EYBlockchain/nightfall_4_CE/blob/master/doc/nf_4.md#client-apis# Nightfall Client Playbook — Plume Testnet
