 While test resources provided by `@QuarkusTestResource` are available either globally or restricted to the annotated test class (`restrictToAnnotatedClass`), the annotation `@WithTestResources` allows to additionally group tests by test resources for execution.
 `@WithTestResources` has a `scope` property that takes a `TestResourceScope` enum value:
 
-- `TestResourceScope.MATCHING_RESOURCES` (default) +
-Quarkus will group tests with the same test resources and run them together. After a group has been executed, all test resources will be stopped, and the next group will be executed.
-- `TestResourceScope.RESTRICTED_TO_CLASS` +
-The test resource is available only for the annotated test class and will be stopped after the test class has been executed. This is equivalent to using @QuarkusTestResource with restrictToAnnotatedClass = true.
-- `TestResourceScope.GLOBAL` +
-The test resource is available globally.
-This is equivalent  to using `@QuarkusTestResource` with `restrictToAnnotatedClass = false`.
-
-NOTE: `@QuarkusTestResource` is merely a convenient extension of `@WithTestResources` for the use of global test resources
-
-BELOW TO EDIT: +
-I don't know the behaviour when different scopes are mixed 🤷‍♂️Example:
-```java
-@WithTestResources(value = TestResourceA.class, scope = TestResourceScope.MATCHING_RESOURCES)
-@WithTestResources(value = TestResourceB.class, scope = TestResourceScope.RESTRICTED_TO_CLASS)
-@WithTestResources(value = TestResourceC.class, scope = TestResourceScope.GLOBAL)
-class TestClass(){}
-```
-Also maybe add a use case example for why this annotation got introduced and what for the different scopes are useful, as we currently only use GLOBAL because of time reason.
+- `TestResourceScope.MATCHING_RESOURCES` (default): Quarkus will group tests with the same test resources and run them together. After a group has been executed, all test resources will be stopped, and the next group will be executed.
+- `TestResourceScope.RESTRICTED_TO_CLASS`: The test resource is available only for the annotated test class and will be stopped after the test class has been executed.
+- `TestResourceScope.GLOBAL`: Test resources apply to all tests in the testsuite
+
+Quarkus needs to restart if one of the following is true:
+
+- At least one the existing test resources is restricted to the test class
+- At least one the next test resources is restricted to the test class
+- Different {@code MATCHING_RESOURCE} scoped test resources are being used
