 ## Setup with template: "Prisma Pulse DB Only"
 
+This section provides step-by-step instructions for setting up a Pulse-ready PostgreSQL database using the Railway template called: [Prisma Pulse DB Only](https://railway.app/template/pulse-pg). 
+
+The template consists of two [services](https://docs.railway.app/reference/services):
+- **Postgres**: A PostgreSQL database that you'll be able to use with Prisma Pulse after going through the setup instructions.
+- **restart-and-delete-me**: This service contains a [script](https://github.com/prisma/pulse-railway-pg-config/blob/main/config-db.ts) that's executed once and configures the PostgreSQL database to make it usable with Prisma Pulse. Once the script has been executed, the instructions will tell you to delete this service since it won't be needed any more.
+
 1. Deploy the [template](https://railway.app/template/pulse-pg) on Railway.
 2. Click on the service called **restart-db-then-delete-me**.
 3. You will see a list of deployments under the **Deployments** tab.
