After installing Outlink follow the steps below to add external / affiliate links to any product on your site:
1. Login to Shopify (Ignore, if done).
2. (Important) Select a product you want to add external link and go to the product edit page wherein you can edit the product details (name, description, price, etc.). Here you will see the 'Outlink' button under 'More Actions...'.
3. 'Edit Outlinks' screen is displayed. Enter the external link URL, enter label for external link button, toggle activate 'On' and click 'Save'.
4. An external link is added to the product. To verify, visit the product page on Shopify. The 'Add to Cart' button will be replaced with the external link button. Clicking on this button will redirect the user to the external site in a new tab.
