Home page URL change

HI!

I'm migrating from joomla to ОС. Currently my old site store page located at www.mysite.com/shop and home page is located at www.mysite.com

Please help to change my new site home page to mysite.com/shop, categories to www.mysite.com/shop/category, products to www.mysite.com/shop/category/product as for www.mysite.com it has be linked to specific informatom page.

Thanks for your help!

So you have opencart installed in the /shop directory already? or in the root?

Need more info....

We use root directory since if we move it to /shop all articles will have /shop prefix and this is not OK for us.
