+ * Add Kobble login to your page.
+ *
+ * ### Setup
+ *
+ * #### Callback URL
+ *
+ * Authorize this callback URL in your [Kobble application settings](https://kobble.io).
+ *
+ * ```
+ * https://example.com/api/auth/callback/kobble
+ * ```
+ *
+ * #### Configuration
+ *```js
+ * import Auth from "@auth/core"
+ * import Kobble from "@auth/core/providers/kobble"
+ *
+ * const request = new Request(origin)
+ * const response = await Auth(request, {
+ *   providers: [Kobble({ clientId: KOBBLE_CLIENT_ID, clientSecret: KOBBLE_CLIENT_SECRET, tenant: KOBBLE_TENANT })],
+ * })
+ * ```
+ *
+ * :::tip
+ * The `tenant` option corresponds to your customer portal domain.
+ * :::
+ *
+ * ### Resources
+ *
+ *  - [Kobble OAuth documentation](https://docs.kobble.io/product/authentication/overview)
+ *
+ * ### Notes
+ *
+ * By default, Auth.js assumes that the Kobble provider is
+ * based on the [OAuth 2](https://www.rfc-editor.org/rfc/rfc6749.html) specification.
+ *
+ * :::tip
+ * Enable the `openid` option in scope if you want to save the users email address on sign up.
+ * :::
+ *
+ * :::tip
+ *
+ * The Kobble provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/kobble.ts).
+ * To override the defaults for your use case, check out [customizing a built-in OAuth provider](https://authjs.dev/guides/providers/custom-provider#override-default-options).
+ *
+ * :::
+ *
+ * :::info **Disclaimer**
+ *
+ * If you think you found a bug in the default configuration, you can [open an issue](https://authjs.dev/new/provider-issue).
+ *
+ * Auth.js strictly adheres to the specification and it cannot take responsibility for any deviation from
+ * the spec by the provider. You can open an issue, but if the problem is non-compliance with the spec,
+ * we might not pursue a resolution. You can ask for more help in [Discussions](https://authjs.dev/new/github-discussions).
