+As well as in Solidity, at Stylus, it's frequently helpful to know whether a contract supports an interface you'd like to use.
+https://eips.ethereum.org/EIPS/eip-165[`ERC-165`] is a standard that helps do runtime interface detection.
+Contracts provide helpers both for implementing ERC-165 in your contracts and querying other contracts:
 
-* xref:api:utils.adoc#IERC165[`IERC165`] — this is the ERC-165 interface that defines xref:api:utils.adoc#IERC165-supportsInterface-bytes4-[`supportsInterface`]. When implementing ERC-165, you'll conform to this interface.
-* xref:api:utils.adoc#ERC165[`ERC165`] — inherit this contract if you'd like to support interface detection using a lookup table in contract storage. You can register interfaces using xref:api:utils.adoc#ERC165-_registerInterface-bytes4-[`_registerInterface(bytes4)`]: check out example usage as part of the ERC-721 implementation.
-* xref:api:utils.adoc#ERC165Checker[`ERC165Checker`] — ERC165Checker simplifies the process of checking whether or not a contract supports an interface you care about.
-* include with `using ERC165Checker for address;`
-* xref:api:utils.adoc#ERC165Checker-_supportsInterface-address-bytes4-[`myAddress._supportsInterface(bytes4)`]
-* xref:api:utils.adoc#ERC165Checker-_supportsAllInterfaces-address-bytes4---[`myAddress._supportsAllInterfaces(bytes4[\])`]
+* https://docs.rs/openzeppelin_stylus/utils/introspection/erc165/trait.IErc165.html[`IERC165`] — this is the ERC-165 trait that defines https://docs.rs/openzeppelin_stylus/utils/introspection/erc165/trait.IErc165.html#tymethod.supports_interface[`supportsInterface`]. In order to implement ERC-165 interface detection, you should manually expose https://docs.rs/openzeppelin_stylus/utils/introspection/erc165/trait.IErc165.html#tymethod.supports_interface[`supportsInterface`] function in your contract.
