1. From the app, either Create or Edit Individual Tabs.
2. Under Tab Settings, select the Heading to use as Tab Title.
3. From your Shopify admin, go to Products > All products
4. Click the name of the product that you want to add Individual Tabs to.
5. Under Description, add and/or highlight the text you want to use as Tab Title and format it to the Heading you have selected at Step 2.
6. Content under each formatted Heading will become content in their respective tabs.
7. Click Save.
The Individual Tabs you have just created will be reflected in your shop as long as you have enabled them and turned on publish at '2. Style and Publish'.
