-  * `APP_WATCHER_URL` is used by mobymask-app to make GQL queries
-  * `DEPLOYED_CONTRACT` and `CHAIN_ID` is used by mobymask-app in app config when creating messgaes for L2 txs
-  * `RELAY_NODES` is used by the web-apps to connect to the relay nodes (run in watcher)
-* NOTE:
-  * Stack Orchestrator needs to be run in [`dev`](/docs/CONTRIBUTING.md#install-developer-mode) mode to be able to edit the env file
-  * If watcher is running on the host machine, use `host.docker.internal` as the hostname to access the host port
+Create and update an env file to be used in the next step ([defaults](../../config/watcher-mobymask-v2/mobymask-params.env)):
+
+  ```bash
+  # Set relay nodes to be used by the web-app
+  CERC_RELAY_NODES=["/ip4/127.0.0.1/tcp/9090/ws/p2p/12D3KooWSPCsVkHVyLQoCqhu2YRPvvM7o6r6NRYyLM5zeA6Uig5t"]
+
+  # Also add if running MobyMask app:
+
+  # External watcher endpoint (to check if watcher is up)
+  CERC_WATCHER_HOST=
+  CERC_WATCHER_PORT=
+
+  # Watcher endpoint used by the app for GQL queries
+  CERC_APP_WATCHER_URL="http://127.0.0.1:3001"
+
+  # Set deployed MobyMask contract address to be used in MobyMask app's config
+  CERC_DEPLOYED_CONTRACT=
+
+  # L2 Chain ID used by mobymask web-app for L2 txs
+  CERC_CHAIN_ID=42069
+  ```
+
+* NOTE: If watcher is running on the host machine, use `host.docker.internal` as the hostname to access the host port
 
 ### Deploy the stack
 
 For running mobymask-app
 ```bash
-laconic-so --stack mobymask-v2 deploy --include mobymask-app up
+laconic-so --stack mobymask-v2 deploy --include mobymask-app --env-file <PATH_TO_ENV_FILE> up
+
+# Runs on host port 3002
 ```
 
 For running peer-test-app
 ```bash
-laconic-so --stack mobymask-v2 deploy --include peer-test-app up
+laconic-so --stack mobymask-v2 deploy --include peer-test-app --env-file <PATH_TO_ENV_FILE> up
+
+# Runs on host port 3003
 ```
 
 To list down and monitor the running containers:
 
 ```bash
+laconic-so --stack mobymask-v2 deploy --include [mobymask-app | peer-test-app] ps
+
 docker ps
 
 # Check logs for a container
 docker logs -f <CONTAINER_ID>
 ```
 
+## Demo
+
+Follow the [demo](./demo.md) to try out the MobyMask app with L2 chain
