+The contract will also need to register the new SRC5 interface IDs in order to continue declaring support for those interfaces.
 We can create a migration initializer to handle this which needs to be called after the contract upgrade.
 
 TIP: OpenZeppelin's Contracts for Cairo already provides the interface IDs of common interfaces in the API section (like {isrc6}).

-Note that SRC5 interface IDs are calculated differently than those in ERC165.
-Because of this, contracts that leverage introspection (like ERC721) will also need to be upgraded in order to query the correct interface IDs.

-Deployed contracts with upgradeability should also be carefully tested before migrating.
+Note that deployed contracts with upgradeability should also be carefully tested before migrating.
 Upgradeable contracts will likely include some form of a permissions mechanism for upgrading contracts.
 Take extreme care with ensuring admins are not inadvertantly stripped of their permissions.
