-Support for discovering tests and test suites using reflection.
+Support for discovering and running tests and test suites using reflection.
 
-This package follows the xUnit style where each class is a test suite, and each
-method with the name prefix `test_` is a single test.
+This package follows an xUnit style where each class can be a test suite.
+Test methods within the class are discovered reflectively based on their names or annotations.
 
-Methods with names starting with `test_` are run using the `test()` function with
-the corresponding name. If the class defines methods `setUp()` or `tearDown()`,
-they are executed before / after each test correspondingly, even if the test fails.
+## Usage
 
-Methods with names starting with `solo_test_` are run using the `solo_test()` function.
+A test file will typically have a `main` function that kicks off the test loader, and one or more classes annotated with
+`@reflectiveTest`.
 
-Methods with names starting with `fail_` are expected to fail.
+Here is a simple example:
 
-Methods with names starting with `solo_fail_` are run using the `solo_test()` function
-and expected to fail.
+```dart
+import 'package:test/test.dart';
+import 'package:test_reflective_loader/test_reflective_loader.dart';
 
-Method returning `Future` class instances are asynchronous, so `tearDown()` is
-executed after the returned `Future` completes.
+void main() {
+  defineReflectiveSuite(() {
+    defineReflectiveTests(MyTestClass);
+  });
+}
+
+@reflectiveTest
+class MyTestClass {
+  void test_simpleSuccess() {
+    expect(true, isTrue);
+  }
+
+  @failingTest
+  void test_expectedToFail() {
+    expect(false, isTrue);
+  }
+
+  @skippedTest
+  void test_skipped() {
+    // This test won't be run.
+  }
+
+  void setUp() {
+    // setUp is called before each test.
+    print('setting up');
+  }
+
+  void tearDown() {
+    // tearDown is called after each test.
+    print('tearing down');
+  }
+}
+```
+
+To run the tests, you would execute your test file with `dart test`.
+
+### Test Discovery
+
+The `defineReflectiveSuite` and `defineReflectiveTests` functions are used to discover and define tests.
+
+* `defineReflectiveSuite`: This function creates a test suite. It takes a closure as an argument, and within that
+  closure, you can define tests and other nested suites. This allows you to group related tests together.
+
+* `defineReflectiveTests`: This function tells the test runner to look for tests in a given class. The class must be
+  annotated with `@reflectiveTest`. The test runner will then reflectively look for methods in that class that are
+  considered tests (see below).
+
+### Test Suites
+
+Test suites are classes annotated with `@reflectiveTest`. The loader will instantiate this class for each test method,
+so tests are isolated from each other.
+
+### Test Methods
+
+The loader discovers tests in a few ways:
+
+* Methods whose names start with `test_` are treated as tests.
+* Methods whose names start with `fail_` are treated as tests that are expected to fail.
+* Methods whose names start with `skip_` are skipped.
+
+### Annotations
+
+* `@failingTest`: Marks a test that is expected to fail. This is useful for tests that demonstrate a bug that has not
+  yet been fixed.
+* `@skippedTest`: Marks a test that should be skipped and not run.
+* `@soloTest`: Can be applied to a test class or a test method to indicate that only this test (or the tests in this
+  class) should be run. If multiple tests/classes have this annotation, they will all run.
+
+### `setUp` and `tearDown`
+
+If a test class defines a `setUp()` method, it will be run before each test method in that class. If it defines a
+`tearDown()` method, it will be run after each test method, even if the test fails. These are useful for setting up and
+cleaning up test fixtures. Both `setUp()` and `tearDown()` can be `async` and return a `Future`.
+
+### Asynchronous Tests
+
+If a test method, `setUp()`, or `tearDown()` returns a `Future`, the test runner will wait for the future to complete.
+The `tearDown` method (if any) will be executed after the test method and its `Future` completes.
