-## Patchwork
+## Enable Patchwork
 
 [Patchwork](https://github.com/antecedent/patchwork) is a library that enables temporarily overwriting user-defined functions and static methods. This means you can better isolate your system under test by mocking your plugin's functions that are tested elsewhere. If Patchwork is turned on, WP_Mock will transparently use it behind the scenes. For most use cases, you won't need to worry about using it directly.

-## Strict Mode
+## Enable Strict Mode
 
 WP_Mock has a strict mode that developers may optionally enable. By default, it is disabled. If enabled, strict mode will cause tests to fail if they use previously mocked functions without first explicitly declaring an expectation for how that function will be used. This provides an easy way to enforce an extra layer of specificity in unit tests.

+## Extend WP_Mock Test Case
+
+Once you have set up WP_Mock as outlined above, you should use the `WP_Mock\Tools\TestCase` class as your base test case class in your PHPUnit tests. This class extends PHPUnit's own `TestCase` class, with some helper methods but also methods that help WP_Mock to function properly. You should always extend `WP_Mock\Tools\TestCase` instead of `PHPUnit\Framework\TestCase` when using WP_Mock.
+
+```php
+
+use WP_Mock\Tools\TestCase;
+
+class MyClassTest extends TestCase
+{
+    // your test methods   
+}
+
+```
+
+If you **do not** wish to extend WP_Mock own test case, then you should make sure to call `WP_Mock::setUp()` and `WP_Mock::tearDown()` in your test case's `setUp()` and `tearDown()` methods respectively. This is not recommended though.
+
+```php
+
+use PHPUnit\Framework\TestCase;
+
+class MyClassTest extends TestCase
+{
+    public function setUp() : void
+    {
+        parent::setUp()
+
+        WP_Mock::setUp();

-Note how in the above test class `WP_Mock\Tools\TestCase` was extended instead of `PHPUnit\Framework\TestCase`. This is because WP_Mock provides a custom test case class that extends PHPUnit's test case class and adds additional functionality to it.
