Hello,
I'm Alex, experienced e-commerce developer.
So you guys need 2 things:
1. Show full URL information when user shares a page/product, etc. Need to add some information what social channels should take from the URL. I've done this before so I know how to do it.
2. Add "About" button to the header menu.
If this is it, then let's have a chat to proceed.
Thanks!
Alex
