 ### Use the RPC provider to connect to a well-known network
 
 The following example illustrates how you can use the `rpc-provider` to connect to a well-known network such as Polkadot, Kusama, Westend, or Rococo.
 
 ```js
 import { ScProvider, WellKnownChain } from "@polkadot/rpc-provider/substrate-connect";
+import * as Sc from "@substrate/connect";
 import { ApiPromise } from "@polkadot/api";
 // Create the provider for a known chain
-const provider = new ScProvider(WellKnownChain.westend2);
+const provider = new ScProvider(Sc, WellKnownChain.westend2);
 // Stablish the connection (and catch possible errors)
 await provider.connect();
 // Create the PolkadotJS api instance
