+## Run
+
+* Remove any existing containers / volumes:
+
+  ```bash
+  docker-compose down -v --remove-orphans
+  ```
+
+* Spin up an access node and three data nodes using [docker-compose.test.yml](./docker-compose.test.yml):
+
+  ```bash
+  docker-compose -f docker-compose.test.yml up
+  ```
+
+  Following final output should be seen on all the nodes:
+
+    ```
+    LOG:  TimescaleDB background worker launcher connected to shared catalogs
+    ```
+
+* Edit [startup_script.sh](./scripts/startup_script.sh) to change the number of migrations to be run:
+
+  ```bash
+  ./goose -dir migrations/vulcanizedb postgres "$VDB_PG_CONNECT" up-to 21
+  ```
+
+* In another `ipld-eth-db` terminal window, build an image `migrations-test` using [Dockerfile](./db/Dockerfile):
+
+  ```bash
+  docker build -t migrations-test -f ./db/Dockerfile .
+  ```
+
+* After the access and data nodes have spun up, start a container using `migrations-test` image to run the db migrations:
+
+  ```bash
+  # Here, we are running the container using host network.
+  # So connect to access node on 127.0.0.1:8066
+  docker run --rm --network host -e DATABASE_USER=postgres -e DATABASE_PASSWORD=password -e DATABASE_HOSTNAME=127.0.0.1 -e DATABASE_PORT=8066 -e DATABASE_NAME=vulcanize_testing_v4 migrations-test
