+# Doma Spring Boot Sample with TestContainers
+
+This sample demonstrates how to use [TestContainers](https://www.testcontainers.org/) with Doma and Spring Boot.
+
+## Running the Sample
+
+To run this sample, you need:
+- Java 17 or later
+- Maven
+- Docker (for running TestContainers)
+
+### Build and Run Tests
+
+This project uses the Maven Wrapper, so you don't need to install Maven separately.
+
+```bash
+./mvnw clean test
+```
+
+### Run with TestContainers
+
+```bash
+./mvnw spring-boot:test-run
+```
+
+This will start the application with a PostgreSQL container.
+
+## Features Demonstrated
+
+- Using TestContainers to start a PostgreSQL database for tests
+- Spring Boot's native TestContainers integration with `@ServiceConnection`
+- Using TestContainers at development time with `SpringApplication.from()`
+- Running Doma queries against a real PostgreSQL database in tests
+- Configuration for PostgreSQL database in both development and test environments
