 Kass is a multiplatform library, supporting JVM, Android, iOS (x64, ARM, Simulator-ARM), JS.
 
 ## Usage
-`assert()` and `assume()` both return objects that allow you to write expectations in a fluent style.
-`assert()` returns an `Assertion` object, while `assume()` returns an `Assumption` object.
+`assertThat(subject, statement)` and `assumeThat(subject, statement)` both evaluate the given subject against a given statement, which can be written in a fluent style using the provided statement functions.
+
 When an assumption fails, the test execution will stop at that point, throwing a `FailedAssumption` error.

+To catch this error and fail silently, use `testScenario(subjects)` which takes a collection that 
 provides subjects and a lambda executed on a Scenario object that wraps each subject.
-Use testHypothesis() to run a single test without an implicit subject.

 When an assertion fails, tests fail normally.
