Make sure that you removed old code quality and pipeline configuration files or folders, e.g. rector.php, .php-cs-fixer.php, .phpstan.
Make sure, your composer.json does not have any dev-requirements on explicit code-quality packages (like phpunit/phpunit, rector/rector, typo3/coding-standards and so on).
Make sure your .gitignore file includes the folder .Build and the file composer.lock.
.Build
composer.lock
Install the TYPO3 coding-standards package.
composer require --dev --with-all-dependencies mediatis/typo3-coding-standards
Run the kickstart script to install configuration files. Pass the lowest TYPO3 major version number that your extension supports.
./.Build/bin/mediatis-typo3-coding-standards-setup
Start ddev in the extension folder
ddev start
