+## Wallet module for connecting MetaMask Connect EVM to web3-onboard
+
 The MetaMask Web3-Onboard module provides a reliable, secure, and seamless connection from your dapp to the MetaMask browser extension and MetaMask Mobile.
-See [MetaMask SDK Developer Docs](https://docs.metamask.io/wallet/how-to/connect/set-up-sdk/)
+
+This module uses [MetaMask Connect EVM](https://docs.metamask.io/metamask-connect/evm/) (`@metamask/connect-evm`) under the hood — the successor to the legacy `@metamask/sdk`. The integration surface for `@web3-onboard/metamask` is unchanged: the legacy options below are mapped to their MetaMask Connect EVM equivalents internally so existing dapps keep working without code changes.
