 ## Rule Sets
 
-The plugin groups its rules into predefined sets, so that you may enable exactly the transformations you need. You may register these sets in your project's `rector.php` file, and combine as many of them as you wish.

-### Coding Style
+The plugin provides a predefined rule set: `PestSetList::CODING_STYLE`. You may register this set in your project's `rector.php` file.
 
 The `CODING_STYLE` set rewrites raw PHP assertions into Pest's expressive, built-in matchers, and simplifies redundant expectation patterns. For example, it converts `expect(count($array))->toBe(3)` into `expect($array)->toHaveCount(3)`.
 
-It also merges consecutive expectations on the same value into a single, fluent chain, and orders type checks first within each chain, so that your assertions read from the most general to the most specific:

-### Pest Version Upgrades
-
-To upgrade your test suite between major Pest versions, you may reach for the level sets provided by `PestLevelSetList`. Unlike the sets above, a level set is cumulative: it applies every migration up to and including the version you target, so that a suite on an older version arrives fully up to date in a single pass:
-
-```php
-use Pest\Rector\Set\PestLevelSetList;
-use Rector\Config\RectorConfig;
-
-// Upgrade from Pest v2 to v3
-return RectorConfig::configure()
-    ->withPaths([__DIR__ . '/tests'])
-    ->withSets([PestLevelSetList::UP_TO_PEST_30]);
-```
-
-To upgrade to Pest v4, target `UP_TO_PEST_40` instead. As it is cumulative, it includes every transformation from `UP_TO_PEST_30` as well, so you may upgrade from either Pest v2 or v3 in one step:
-
-```php
-use Pest\Rector\Set\PestLevelSetList;
-use Rector\Config\RectorConfig;
-
-return RectorConfig::configure()
-    ->withPaths([__DIR__ . '/tests'])
-    ->withSets([PestLevelSetList::UP_TO_PEST_40]);
-```
-
-Of course, if you would rather apply the migration rules for a single version in isolation, the individual `PestSetList::PEST_30` and `PestSetList::PEST_40` sets remain available as well.
