Is the documentation system on available in cs-cart?

See: CS-Cart Documentation — CS-Cart 4.15.x documentation

Is this system available in CS-Cart 3?

I am in need of an article system with good SEO, to run with CS-CART3.

Is the blog system available in CS-cart 3?

If something different than CS-CART is used for documentation and blog, then can you please explain what is used?

Seems the Documentation part IS a CS-Cart controlled site, however, this appears to be custom functionality developed for their own system. Not sure why they haven't included it in the software because it really does lack a real CMS.

As for the Blog, this is running WordPress.
