# How to Start

Since the Happ app does not send data on its own, you need to specify the [**Provider ID**](/getting-started/provider-id.md) manually — using any of the methods described in the [**Provider ID**](/getting-started/provider-id.md) instructions.

Also, **don’t forget to add the subscription domain** to your personal account on the [happ-proxy.com](https://happ-proxy.com) website. Detailed instructions can be found in the **"Adding a Domain"** section.

Once these steps are completed, Happ will automatically check for the presence and premium status of the specified **Provider ID** when adding a subscription. The premium status check is performed **once per day**, so please be patient.
