# WherebyClient

```jsx
import { WherebyClient } from "@whereby.com/core";

const client = new WherebyClient();
```

The WherebyClient is the main entry point for the Core SDK. It acts as a wrapper around the underlying state store and service layer, and gives you access to the specialized client classes.

Creating a WherebyClient automatically sets up the internal store and services. From there, you can retrieve the specific clients you need:

* LocalMediaClient → manage camera and microphone
* RoomConnectionClient → join/leave rooms, subscribe to remote participants, any in room actions
