+
+Instructions for running the laconic shopify
+
+## Setup
+
+* Clone the stack repo:
+
+  ```bash
+  laconic-so fetch-stack git.vdb.to/cerc-io/testnet-laconicd-stack
+  ```
+
+* Clone the laconic-shopify respository:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconic-shopify setup-repositories
+  ```
+
+* Build the container image:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconic-shopify build-containers
+  ```
+
+  This should create the `cerc/laconic-shopify-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-shopify deploy init --output laconic-shopify-spec.yml
+  ```
+
+* Create a deployment from the spec file:
+
+  ```bash
+  laconic-so --stack ~/cerc/testnet-laconicd-stack/stack-orchestrator/stacks/laconic-shopify deploy create --spec-file laconic-shopify-spec.yml --deployment-dir laconic-shopify-deployment
+  ```
+
+## Configuration
+
+* Inside the `laconic-shopify-deployment` deployment directory, open `config.env` file and set following env variables:
+
+  ```bash
+  # Shopify GraphQL URL
+  CERC_SHOPIFY_GRAPHQL_URL='https://6h071x-zw.myshopify.com/admin/api/2024-10/graphql.json'
+
+  # Access token for Shopify API
+  CERC_SHOPIFY_ACCESS_TOKEN=
+
+  # Delay for fetching orders in milliseconds
+  CERC_FETCH_ORDER_DELAY=10000
+
+  # URL for the laconic faucet
+  CERC_FAUCET_URL='http://host.docker.internal:3000/'
+
+  # Number of line items per order in Get Orders GraphQL query
+  CERC_ITEMS_PER_ORDER=10
+  ```
+
+## Start the deployment
+
+  ```bash
+  laconic-so deployment --dir laconic-shopify-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>
+  ```
+
+## Clean up
+
+* Stop the `laconic-shopify-faucet` service running in the background:
+
+  ```bash
+  # Stop the docker container
+  laconic-so deployment --dir laconic-shopify-deployment stop
+  ```
+
+* To stop the service and also delete data:
+
+  ```bash
+  # Stop the docker containers
+  laconic-so deployment --dir laconic-shopify-deployment stop --delete-volumes
+
+  # Remove deployment directory (deployment will have to be recreated for a re-run)
+  rm -r laconic-shopify-deployment
+  ```
