How to update Zest theme?

A guide to update Zest theme
The most up-to-date versions of all themes are available on Shopify Theme Store.
If you've purchased a paid theme on Shopify Theme Store, you can add the updated version for free.
If you've purchased a paid theme from a third-party theme designer, we highly suggest you contact that theme developer or author for updates.
When a theme update is available, a notification will appear below the theme in your Shopify Admin.
Click on the notification to read more details, and select Add to theme library to add the updated version to your theme library, or select View release notes to read the new release details.
All code customizations in your theme are not transferred to the new theme version by default. You need to duplicate and move the code to the new version yourself.
