+
+## Installation
+
+You can install the package via composer:

+```bash
+composer require feature-ninja/testing-matrix
+```
+
+## Usage
+
+Create a testing matrix from an array:

+```php
+use FeatureNinja\TestingMatrix\Matrix;
+
+$matrix = Matrix::create([
+    'a' => [1, 2],
+    'b' => [3, 4],
+]);
+
+assert(iterator_to_array($matrix) === [
+    'a=1 b=3' => [1, 3],
+    'a=1 b=4' => [1, 4],
+    'a=2 b=3' => [2, 3],
+    'a=2 b=4' => [2, 4],
+]);
+```
+
+Usage in PHPUnit:
+
+```php
+use FeatureNinja\TestingMatrix\Matrix;
+use PHPUnit\Framework\Attributes\DataProvider;use PHPUnit\Framework\Attributes\Test;
+use PHPUnit\Framework\TestCase;
+
+final class ExampleTest extends TestCase
+{
+    public static function example_data_provider(): Generator
+    {
+        yield from Matrix::create([
+            'a' => [1, 2],
+            'b' => [3, 4],
+        ]);
+    }
+
+    #[Test]
+    #[DataProvider('examples')]
+    public function example(int $a, int $b): void
+    {
+        // ...
+    }
+}
