+
+Instructions for running the laconic faucet
+
+## Setup
+
+* Clone the stack repo:
+
+  ```bash
+  laconic-so fetch-stack git.vdb.to/cerc-io/testnet-laconicd-stack
+  ```
+
+* Clone the laconic-faucet respository:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconic-faucet setup-repositories
+  ```
+
+* Build the container image:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconic-faucet build-containers
+  ```
+
+  This should create the `cerc/laconic-faucet` image locally
+
+## Create a deployment
+
+* Create a spec file for the deployment:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconic-faucet deploy init --output laconic-faucet-spec.yml
+  ```
+
+* Edit `network` in the spec file to map container ports to host ports as required:
+
+  ```bash
+  network:
+    ports:
+      laconic-faucet:
+        - '3000:3000'
+  ```
+
+* Create a deployment from the spec file:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconic-faucet deploy create --spec-file laconic-faucet-spec.yml --deployment-dir laconic-faucet-deployment
+  ```
+
+## Configuration
+
+* Inside the `laconic-faucet-deployment` deployment directory, open `config.env` file and set following env variables:
+
+  ```bash
+  # Private key of a funded faucet account
+  CERC_FAUCET_KEY=
+
+  # Optional
+
+  # laconicd RPC endpoint (default: http://laconicd:26657)
+  CERC_LACONICD_RPC_ENDPOINT=
+
+  # laconicd chain id (default: laconic_9000-1)
+  CERC_LACONICD_CHAIN_ID=
+
+  # Amount of tokens to transfer on a single request (default: 1000000)
+  CERC_TRANSFER_AMOUNT=
+
+  # Transfer limit for an address within a period (default: 3000000)
+  CERC_PERIOD_TRANSFER_LIMIT=
+  ```
+
+## Start the deployment
+
+  ```bash
+  laconic-so deployment --dir laconic-faucet-deployment start
+  ```
+
+## Check status
+
+* To list down and monitor the running container:
+
+  ```bash
+  # With status
+  docker ps
+
+  # Check logs for a container
+  docker logs -f <CONTAINER_ID>
+  ```
+
+## Run
+
+* Request tokens from the faucet for an account:
+
+  ```bash
+  curl -X POST http://localhost:3000/faucet \
+    -H "Content-Type: application/json" \
+    -d '{"address": "<laconicd_address>"}'
+
+  # Expected output:
+  # {"success":true,"txHash":"<tx_hash>"}
+  ```
+
+## Clean up
+
+* Stop the `laconic-faucet` service running in the background:
+
+  ```bash
+  # Stop the docker container
+  laconic-so deployment --dir laconic-faucet-deployment stop
+  ```
+
+* To stop the service and also delete data:
+
+  ```bash
+  # Stop the docker containers
+  laconic-so deployment --dir laconic-faucet-deployment stop --delete-volumes
+
+  # Remove deployment directory (deployment will have to be recreated for a re-run)
+  rm -r laconic-faucet-deployment
+  ```
