# Rules

This Shopify app has some rules that need to be fulfilled.

* Do not change the headers in the downloaded CSV file.
* Paste each condition exactly as copied into the **Products must match** column.
* For single conditions, remove any trailing comma (**,**) to prevent import errors.
* If there is more than one condition, separate them with commas.
