 NOTE: `@ConditionalOnBean` and `@ConditionalOnMissingBean` do not prevent `@Configuration` classes from being created.
 The only difference between using these conditions at the class level and marking each contained `@Bean` method with the annotation is that the former prevents registration of the `@Configuration` class as a bean if the condition does not match.
 
+TIP: When declaring a `@Bean` method, provide as much type information as possible in the method's return type.
+For example, if your bean's concrete class implements an interface the bean method's return type should be the concrete class and not the interface.
+Providing as much type information as possible in `@Bean` methods is particularly important when using bean conditions as their evaluation can only rely upon to type information that's available in the method signature.
