 * Drupal 8's minimum requirement is phpdocumentor/reflection-docblock:2.0.4 but at least 3.0 is required by this module. If you get the error  "Your requirements could not be resolved to an installable set of packages" it may be because you are running reflection-docblock version 2. You can update `phpdocumentor/reflection-docblock` with the following command: `composer update phpdocumentor/reflection-docblock --with-dependencies`.
