-The last line indicating the `__gap` storage slot is what's most important. `__gap` has a total of 50 storage slots reserved. You **MUST** verify that the array length of __gap`, in this case `38`, is equal to `50 - __gap.Slot`. In this case, the `Slot` column for `__gap` shows 12, so the layout is correct.

 ## Reinitializers
 In case you need to reinitialize your contract, you'll need to create a reinitializer.
