WP education theme

Hello,

I considered purchasing the woocommerce add-on,
but on the selling page it is suggested to purchase an education theme, and that it will include inside all the learnpress add-ons bundle.

What I can’t seem to figure out – is if I have an existing site, with a theme, I don’t want to change the whole site – only to upgrade the courses platform on it – is it relevant for me? or is it only for new sites?

Also, I can’t find a demo to see how learnpress courses looks with this theme that is offered to be purchased.
