 This demonstrates a small NodeJS client opening a database and connecting PowerSync.
 
-To get started with this example, you need a configured instance of the sync service.
-This example expects the the schema [created in this guide](https://docs.powersync.com/integration-guides/supabase-+-powersync#configuring-powersync),
-which you can follow to start a compatible service.
+To get started with this example, you need a configured instance of the PowerSync Service. The easiest way to get started is to configure a PowerSync Cloud instance, docs [here](https://docs.powersync.com/installation/database-connection#create-a-powersync-cloud-instance).  
+This example expects the schema of our To-Do list example apps; ensure you deploy compatible Sync Rules to your instance which can be found [in our Supabase integration guide](https://docs.powersync.com/integration-guides/supabase-+-powersync#configure-sync-rules).
 
 Being a simple CLI program, this currently doesn't implement authentication. So, you'll need to
 create a [development token](https://docs.powersync.com/installation/authentication-setup/development-tokens#development-tokens) to run this example.
-This demo expects the URL of the PowerSync instance in the `DEMO_ENDPOINT` environment variable,
+This demo expects the URL of your PowerSync instance (this can be copied from the PowerSync Dashboard) in the `DEMO_ENDPOINT` environment variable,
 the development token is read from `DEMO_TOKEN`.
 
-Once you have those values ready, you can use the following command to open a database, connect to PowerSync,
-wait for a first sync and run a simple query.
+Once you have these ready: 
 
+1. Make sure to run `pnpm install` and `pnpm build:packages` in the root of this repo.
+2. Then run the following, inserting your instance URL and developer token:
+```DEMO_ENDPOINT=https://yourinstance.powersync.journeyapps.com DEMO_TOKEN=YOURTOKEN pnpm run start
 ```
-DEMO_ENDPOINT=https://yourinstance.powersync.journeyapps.com DEMO_TOKEN=YOURTOKEN pnpm run start
-```
+This opens the local database, connects to PowerSync, waits for a first sync and then runs a simple query.
