[Bug]: Incorrect Import and Initialization in the Second Example

[MarlonFillho]

In the first line of the second example, the import statement reads from clientai import client, but the client module does not exist in the clientai framework.

To fix this:

1. Update the import statement to match the first example: from clientai import ClientAI.
2. Change line 16 of the second example to properly initialize the client: client = ClientAI("groq", api_key="your-groq-key")

Nice catch, @MarlonFillho!
