Store Migration

Hi,
I am an Etsy store owner YCBTEESHIRTS & GIFTS. I wanted to have another platform, so from what I hear Shopify is one of the best. I have not finished my site yet but so far so good.

It was pretty easy I watched a youtube video on how to transport over from Etsy, and the app popped up so I added it and it did all the work. I'm still confused because am not sure what to do with some things. But overall easy upload of the products.
