 ## Overview
 The [Sui SDK](https://github.com/MystenLabs/sui/tree/main/crates/sui-sdk) is a collection of Rust language JSON-RPC wrapper and crypto utilities you can use to interact with the [Sui Devnet Gateway](../build/devnet.md) and [Sui Full Node](fullnode.md).
 
-The [`SuiClient`](cli-client.md) can be used to create an HTTP (`SuiClient::new_http_client`) or a WebSocket client(`SuiClient::new_ws_client`).  
+The [`SuiClient`](cli-client.md) can be used to create an HTTP or a WebSocket client (`SuiClient::new_rpc_client`).  
 See our [JSON-RPC](json-rpc.md#sui-json-rpc-methods) doc for the list of available methods.
 
 > Note: As of [Sui version 0.6.0](https://github.com/MystenLabs/sui/releases/tag/devnet-0.6.0), the WebSocket client is for [subscription only](pubsub.md); use the HTTP client for other API methods.
