-### Usage
-
-First, create API credentials on Bitget's website.
+### Getting Started
 
 All REST APIs are integrated in each dedicated Rest Client class. See the above table for which REST client to use. If you've upgraded to the Unified Trading Account, you should use the V3 REST APIs and WebSockets.
 
+There are several REST API modules as there are some differences in each API group:
+
+1. `RestClientV3` for the latest V3/UTA APIs (Unified Trading Account) - recommended for new projects.
+2. `RestClientV2` for V2 APIs - use if you haven't upgraded to UTA yet.
+3. Legacy V1 clients (`SpotClient`, `FuturesClient`, `BrokerClient`) - deprecated, migrate to V2 or V3.
+
+More Node.js & JavaScript examples for Bitget's REST APIs & WebSockets can be found in the [examples](./examples) folder on GitHub.

-#### WebSockets
+## WebSockets
 
 All WebSocket functionality is supported via the WebsocketClient. Since there are currently 3 generations of Bitget's API, there are 3 WebsocketClient classes in this Node.js, JavaScript & TypeScript SDK for Bitget.
 
 Use the following guidance to decide which one to use:
 
-- Unified Trading Account / V3 (latest generation):
+- **Unified Trading Account / V3** (latest generation):
   - For receiving data, use the [WebsocketClientV3](./src/websocket-client-v3.ts).
   - For sending orders via WebSockets, use the [WebsocketAPIClient](./src/websocket-api-client.ts).
-- V2 (not upgraded to Unified Trading Account yet)
+- **V2** (not upgraded to Unified Trading Account yet)
   - Use the [WebsocketClientV2](./src/websocket-client-v2.ts).
-- V1 (deprecated)
+- **V1** (deprecated)
   - This is the oldest API group supported by Bitget. You should migrate to V3 or V2 as soon as possible.
   - If you're not ready to migrate, you can use the [WebsocketClientLegacyV1](./src/websocket-client-legacy-v1.ts) class in the meantime.
 
+All WebSocket clients support:
+
+- Event driven messaging
+- Smart WebSocket persistence with automatic reconnection
+- Heartbeat mechanisms to detect disconnections
+- Automatic resubscription after reconnection
+- Error handling and connection monitoring
+- Optional data beautification
