+
+## Setup
+
+* Clone the stack repo:
+
+  ```bash
+  laconic-so fetch-stack git.vdb.to/cerc-io/eth-stack
+  ```
+
+## Create a deployment
+
+* First, create a spec file for the deployment, which will map the stack's ports and volumes to the host:
+
+  ```bash
+  laconic-so --stack ~/cerc/eth-stack/stack-orchestrator/stacks/eth deploy init --output eth-spec.yml
+  ```
+
+* Once you've made any needed changes to the spec file, create a deployment from it:
+
+  ```bash
+  laconic-so --stack ~/cerc/eth-stack/stack-orchestrator/stacks/eth deploy create --spec-file eth-spec.yml --deployment-dir eth-deployment
+  ```
+
+* Inside the `eth-deployment` deployment directory, open `config.env` file and set following env variables:
+
+  ```bash
+  # Optional
+  # Allow unprotected txs
+  CERC_ALLOW_UNPROTECTED_TXS=true
+  ```
+
+## Start
+
+* Start the deployment:
+
+  ```bash
+  laconic-so deployment --dir eth-deployment start
+  ```
+
+## Clean up
+
+* To stop all services running in the background, while preserving chain data:
+
+  ```bash
+  laconic-so deployment --dir eth-deployment stop
+  ```
+
+* To stop all services and also delete chain data:
+
+  ```bash
+  laconic-so deployment --dir eth-deployment stop --delete-volumes
+
+  # Remove the deployment dir
+  sudo rm -rf eth-deployment
+  ```
