How do I set up my navigation / menu ?
To learn about navigation and menus in Shopify, please click here.
Can my header image be a slideshow?
No, but you can add a slideshow to your homepage as shown here. You would need to hire a developer to custom write code for your store if you wanted a slideshow as the header.
Does the theme support variant images ?
Yes! You can have your images swap when selecting variants, as described here.
Can the product images fit the width of the screen ?
No, the theme was not designed for that, you would need to hire a developer to custom write code for your store.
Can I add more fonts ?
Yes, but you would likely need to hire a developer to custom write code for your store.
Can I add a favicon to my theme ?
Yes! Please see this Shopify article for adding your favicon.
How do I change "Add to cart" to "Buy" ?
You can change nearly all text labels in your store by going to Online Store → Themes → ... → Edit language
Can I remove the powered by Shopify link from the footer ?
Yes, this Shopify article explains how.
Can I add a contact form ?
Yes. This will send an email containing the contact information to the store's owner. To use it, create a normal page, like you would for an About Us page, for your contact form. After creating and saving this page, you will see a new drop down appear to allow you to select the contact template for this page.
Does it support Instagram?
Not directly, but you can add a stream of your own instagram feed by using a third party service. You can then add that code into a page (follow Shopify's guide for embedding a video, it's the same process), and show that page as a row on the homepage.
