README.md file confusing

Hello,
Thank you for this module !
According to the readme file, we should use the drush command :
drush migrate-manifest modules/contrib/migrate_wordpress/manifest_wordpress.yml --legacy-db-url=mysql://{dbuser}:{dbpass}@localhost/{dbname}
When I execute it, I get this error message : "The file "modules/contrib/migrate_wordpress/manifest_wordpress.yml" does not exist".
It works on executing instead :
drush migrate-manifest modules/contrib/wp_migrate/manifest_wordpress.yml --legacy-db-url=mysql://{dbuser}:{dbpass}@localhost/{dbname}
Corresponding patch below.
I guess there is no relationship between the https://www.drupal.org/project/wp_migrate module (yours) and the https://www.drupal.org/project/wordpress_migrate module or I miss something.
