+For more information about getting started with Harper and building applications, see our getting started guide.
 
 This template includes the [default configuration](./config.yaml), which specifies how files are handled in your application.
 
 The [schema.graphql](./schema.graphql) is the schema definition. This is the main starting point for defining your database schema, specifying which tables you want and what attributes/fields they should have.
 
-The [routes/index.js](./resources.js) provides a template for defining Fastify routes. You can add more routes to this file as needed.

+
+## Testing
+
+Integration tests live in [`integrationTests/`](./integrationTests) and run against a real, ephemeral Harper instance using [`@harperfast/integration-testing`](https://www.npmjs.com/package/@harperfast/integration-testing). They exercise the REST API for the `TableName` table and the Fastify `/getAll` route.
+
+```sh
+npm run test:integration
+```
+
+> On macOS/Windows, running the tests locally requires loopback address aliases (`npx harper-integration-test-setup-loopback`, needs `sudo`). On Linux (and CI) the full `127.0.0.0/8` range is available by default, so no setup is needed. The GitHub Actions workflow runs the tests on `ubuntu-latest`.
