I'm not sure what you want ? If you just want to have HikaShop in your language, you can get the translation file as explained here:
www.hikashop.com/en/download/languages.html
Well, I wanted to give you the easy solution to translate your content... Falang does not translate the text for you. You have to enter the text in it.
If you want to do without Falang, that's still possible but it's more complex. You need to create several main categories in HikaShop, one per language. Then, create several menu items of the type hikashop category listing, one per language, and assign each one to the corresponding main category with the "associated category". Then, you can have your categories and products in each language category in HikaShop. When you change your language on your website, the menu item will change and thus it will change the categories/products displayed in the menu. But as I said, that's more complex to handle than with Falang.
