 ### Registration
 There are two methods of registration:
-1. Auto detect - this will check the user provided NFT contract for a contract standard it supports. It first checks ERC-721, then ERC-1155, and then if any others are defines those (e.g. custom or future standards) **Note**:  the checking stops on the first successful standard found.

To know which is which, the main contract exposes the provider address, which can be used to retrieve the queriers and then the name/description on each querier.
