 ## Usage
 
-First, create a webhook using the Seam API or Seam Console
-and obtain a Seam webhook secret.
+The Seam API implements webhooks using [Svix](https://www.svix.com).
+This SDK exports a thin wrapper `SeamWebhook` around the svix package.
+Use it to parse and validate [Seam webhook events](https://docs.seam.co/latest/developer-tools/webhooks).
+
+Refer to the [Svix docs on Consuming Webhooks](https://docs.svix.com/receiving/introduction)
+for an in-depth guide on best-practices for handling webhooks in your application.
 
 > [!TIP]
-> This example is for [Express], see the [Svix docs for more examples in specific frameworks](https://docs.svix.com/receiving/verifying-payloads/how).
