Shopify lets you ‘translate’ phrases that are programmed into the user interface
For example change “No products found in this collection” to ‘More gorgeous products coming – check back soon’.
To find out if an item can be translated to into admin/themes, and edit the language file,
Then select the appropriate tab, find the text you want to update, and overwrite it.
Remember to save when you are done, and check the result on the user interface.
