 Thank you very much for taking the time to report a bug to us, we greatly appreciate it! This document is designed to allow Spring Batch users and team members to contribute self-contained projects containing [minimal complete verifiable examples](https://en.wikipedia.org/wiki/Minimal_reproducible_example) for issues logged against the [issue tracker](https://github.com/spring-projects/spring-batch/issues) on GitHub.

 Once you have the minimal complete verifiable example running as expected, you can import it as a Maven project in your favourite IDE. Please make sure to:
 
 * Update the sample as needed to reproduce your issue. We have placed a few TODOs where we expect you to modify the code.
-* Add any dependency that is required to reproduce your issue.
-* Keep the bare minimum code that is required to reproduce your issue. This is very important! Please reduce as much noise as possible to let us focus on the code related to the issue.

-Heads-up: If you think you can reproduce the issue with a JUnit test, that is awesome! The minimal example that we provide
-has a JUnit test that you can edit as needed to reproduce the issue. Moreover, the minimal example we provide uses an in-memory H2 database, but if your issue is related to a specific database, please do not hesitate to add a Docker based test using
-the [Testcontainers](https://www.testcontainers.org) library and the JDBC driver of your database. You can find several examples in the test suite of Spring Batch [here](https://github.com/spring-projects/spring-batch/blob/main/spring-batch-core/src/test/java/org/springframework/batch/core/test/repository/MySQLJobRepositoryIntegrationTests.java).

+
+# What if I use another database than H2?
+
+If your issue is related to a specific database, please start with the same example as in the previous section and add a Docker-based test using the [Testcontainers](https://www.testcontainers.org) library and the JDBC driver of your database.
+
+For example, if you use PostgreSQL, you might add the following dependencies to the `pom.xml` file:
+
+```xml
+<!-- PostgreSQL JDBC driver -->
+<dependency>
+    <groupId>org.postgresql</groupId>
+    <artifactId>postgresql</artifactId>
+    <version>42.6.0</version> <!-- update the version if needed -->
+</dependency>
+
+<!-- Testcontainers module for PostgreSQL -->
+<dependency>
+    <groupId>org.testcontainers</groupId>
+    <artifactId>postgresql</artifactId>
+    <version>1.17.6</version> <!-- update the version if needed -->
+    <scope>test</scope>
+</dependency>
+```
+
+Also, remember to remove the H2 dependency as well, to keep the example as minimal as possible even in terms of dependencies.

+You can find several examples of Docker-based tests in the [test suite of Spring Batch](https://github.com/spring-projects/spring-batch/blob/main/spring-batch-core/src/test/java/org/springframework/batch/core/test/repository), and a specific example for PostgreSQL [here](https://github.com/spring-projects/spring-batch/blob/main/spring-batch-core/src/test/java/org/springframework/batch/core/test/repository/PostgreSQLJobRepositoryIntegrationTests.java).
+
+# What if I use Spring Boot?
+
+If you use Spring Boot, the best way to create a minimal example is to generate a project on [https://start.spring.io](https://start.spring.io).
+
+Here is a quick link to generate a Maven-based Spring Boot application with Spring Batch and H2: [Sample project](https://start.spring.io/#!type=maven-project&language=java&platformVersion=3.0.4&packaging=jar&jvmVersion=17&groupId=com.example&artifactId=demo&name=demo&description=Demo%20project%20for%20Spring%20Boot&packageName=com.example.demo&dependencies=batch,h2).
+
+You can also generate a project on the command line, for example with `cURL`:
+
+```shell
+$>curl https://start.spring.io/starter.tgz -d dependencies=batch,h2 -d type=maven-project -d baseDir=spring-batch-mcve | tar -xzvf -
+```
+
+Once you have downloaded the project, please follow the same steps as in the previous section (edit the sample, zip it without the dependencies, etc).
