In Shopify, you can insert Sections to the frontpage, which can be used to insert custom HTML, like the embedcodes associated to Website Content.
1. Go to Online Store -> Themes -> Customize.
2. Click Add Section.
3. Click Custom Content -> Add.
4. Remove any existing content from the new block, and click Add Content -> Custom HTML.
5. Insert the embedcode(s) you want to the HTML box.
6. Click Save.
This is an easy way to get sliders on your frontpage in Shopify.
