-## Per-group configuration
-
-While CLI flags and the config file define global behavior, individual groups can define their own configuration using `TestConfig`.
-This allows naming, skipping, or scoping tests directly in code without affecting the rest of the suite.
-
-```php
-use MaplePHP\Unitary\{TestConfig, TestCase, Expect};
-
-$config = TestConfig::make("Checkout API")
-    ->withName("checkout")
-    ->withSkip(); // temporarily skip this group
-
-group($config, function (TestCase $case) {
-    // ...
-});
-```
-
-Configurations are immutable, so you can derive variations without side effects:
-
-```php
-group($config->withSubject("Refund flow"), function (TestCase $case) {
-    // ...
-});
-```
-
-Named groups can always be executed in isolation:
-
-```bash
-php vendor/bin/unitary --show=checkout
-```
