How to reuse sylius components


Hello guys,
I recently got to know the Sylius project and I was trying to re-use its components in a separate project (test-only), my goal was to test if I can use the sylius components in a separate project.

Following the documentation (, I was able to install the components and use their classes, but as I do with the tables of the database ?
I installed the doctrine and tried to map the classes, but I did not succeed.

Thank you so much guys.
