How to use these guides

These pages do not only describe plugin features. They focus on problems developers actually face in Spring Boot projects. Each guide provides copyable configuration snippets, checking order, and verification methods that users can apply inside IntelliJ IDEA.

When diagnosing a specific issue, record the IntelliJ IDEA, plugin, and Spring Boot versions first, then follow the checks in order. Framework defaults can change between releases, so verify version-sensitive behavior against the official references linked from each guide.
