+# Ajna Watcher
+
+## Setup
+
+Clone required repositories:
+
+```bash
+laconic-so --stack ajna setup-repositories --git-ssh --pull
+```
+
+Build the container images:
+
+```bash
+laconic-so --stack ajna build-containers
+```
+
+## Deploy
+
+Create a spec file for the deployment:
+
+```bash
+laconic-so --stack ajna deploy init --output ajna-spec.yml
+```
+
+### Ports
+
+Edit `network` in the spec file to map container ports to host ports as required:
+
+```yml
+...
+network:
+  ports:
+    ajna-watcher-db:
+     - 15432:5432
+    ajna-watcher-job-runner:
+     - 9000:9000
+    ajna-watcher-server:
+     - 3008:3008
+     - 9001:9001
+```
+
+### Create a deployment
+
+Create a deployment from the spec file:
+
+```bash
+laconic-so --stack ajna deploy create --spec-file ajna-spec.yml --deployment-dir ajna-deployment
+```
+
+### Configuration
+
+Inside deployment directory, open the `config.env` file  and set following env variables:
+
+```bash
+# External Filecoin (ETH RPC) endpoint to point the watcher to
+CERC_ETH_RPC_ENDPOINT=https://example-lotus-endpoint/rpc/v1
+```
+
+### Start the deployment
+
+```bash
+laconic-so deployment --dir ajna-deployment start
+```
+
+* To list down and monitor the running containers:
+
+  ```bash
+  # With status
+  docker ps -a
+
+  # Check logs for a container
+  docker logs -f <CONTAINER_ID>
+  ```
+
+* Open the GQL playground at <http://localhost:3008/graphql>
+
+  ```graphql
+  # Example query
+  query {
+    _meta {
+      block {
+        hash
+        number
+        timestamp
+      }
+      deployment
+      hasIndexingErrors
+    }
+
+    accounts {
+      id
+      txCount
+      tokensDelegated
+      rewardsClaimed
+    }
+  }
+  ```
+
+## Clean up
+
+Stop all the ajna services running in background:
+
+```bash
+# Only stop the docker containers
+laconic-so deployment --dir ajna-deployment stop
+
+# Run 'start' to restart the deployment
+```
+
+To stop all the ajna services and also delete data:
+
+```bash
+# Stop the docker containers
+laconic-so deployment --dir ajna-deployment stop --delete-volumes
+
+# Remove deployment directory (deployment will have to be recreated for a re-run)
+rm -r ajna-deployment
+```
