Installation

Modules doesn't requires any special dependencies, it uses default Drupal core dependency doctrine/annotation and XMLWriter from php. You can install it as usual.

Composer

If your project is maintained with composer, install via it:

composer require drupal/yandex_yml

Attention! Before module will be stable, better to lock module version for safety. If some methods will change, your code will not be destroyed. Better update it manually and read changelog.
