Why not post in the support forum for help if you cannot work it out?
There is an in depth doc on theme integration. Would be impossible to work 100% with every theme in existence. If that’s too difficult and you don’t want to ask for help or hire someone, there are plenty of woocommerce ready themes available.
Just to add, it’s ‘powerful’ in that you can customise pretty much everything.
I see on your profile you’re a ‘theme developer’ – it’s going to take some amount of effort and research on your part to get started if you’re doing themes from scratch, but it’s not that difficult and lots of other developers manage 🙂 Give it a chance..
