-## Known Issues
-
-Below is a list of known issues when using this extension:
-
-### PHPStan shim does not generate factories, proxies, etc.
-
-This is because the PHPStan shim is included as a phar archive and does therefore not support overriding certain methods in it's namespace. The current known fix for this is to manually load the autoloader that comes with this extension.
-
-Include the autoload.php file in the `autoload_files`-section of your `phpstan.neon`:
-
-```neon
-parameters:
-    autoload_files:
-        - vendor/bitexpert/phpstan-magento/autoload.php
-```
