How can I revert my theme templates files?
When working on your theme files, a situation may arise where you need the ability to revert to a previous version. From within the Shopify theme editor, changes are tracked and you have the ability to select previous versions.
Selecting a previous state allows you to easily revert back if there was an error made while editing your theme files or you find that a third party app modified you theme files that now needs to be removed or modified.
Shopify provides full instructions for this capability located here.
