 #### Asynchronous verification
@@ -35,6 +36,9 @@ await That(sut.Mock.Verify.MyMethod()).Exactly(2.Times()); // Exactly 2 times
 With `Within(TimeSpan timeout)`, you can check whether the expected number of calls occurred within a given time
 interval. This is useful for asynchronous or delayed invocations in the background.
 
+`Within` and `WithCancellation` are available on `AtLeast*`, `Once`, `Twice`, `Exactly`, and `Between`. They are not
+available on `Never` or `AtMost*`, since an upper bound cannot be confirmed by waiting longer.
