Two issues are unclear in documentation

1. Probably outdated examples with @Testcontainers
   Every example contains @Testcontainers annotation. It seems be unnecessary. For example, Spring Initializer generates working test classes without the annotation. (If I'm right, I can create PR with @Testcontainers removal)

2. Two methods to register Container without explanation
   Container can be registered with @org.testcontainers.junit.jupiter.Container annotation or as a Spring @Bean. Which one is better for which case? On one hand, Spring Initializer generates @Bean, so it looks as recommended. On the other hand, Spring Boot Reference begins with @Container, to it looks as primary decision hint. @Container is a bit boilerplate-less, so the hint looks reasonable.
   As a developer, which method should I choose at the beginning?
