+All API groups can be used via a shared `WebsocketClient`. However, to listen to multiple API groups at once, you will need to make one WebsocketClient instance per API group.
 
 The WebsocketClient can be configured to a specific API group using the market parameter. These are the currently available API groups:
 |         API Category         	|        Market       	| Description                                                                                                                                                                                            	|
