Multi-store capabilities of reactioncommerce


Hello to everyone!

I’m looking for more information about multi-store capabilities of reaction-commerce, (as well multi-language (local) and multi-currency), can somebody point me on docs or some posts?

I’m also very interesting about reaction-commerce marketplace (plugins/modules), where I can find list of them?

Does reaction-commerce has migration solutions from Magento/WordPress?

Thank you for help!
