 1. Add a `copy` element to the storage account resource definition. In the `copy` element, you specify the number of iterations and a variable for this loop. The count value must be a positive integer and can't exceed 800.
-2. The `copyIndex()` function returns the current iteration in the loop. You use the index as the name prefix. `copyIndex()` is zero-based. To offset the index value, you can pass a value in the `copyIndex()` function. For example, `copyIndex(1)`.
-3. Delete the `variables` element, because it's not used anymore.
-4. Delete the `outputs` element. It's no longer needed.
