+ * Add iRacing login to you page.
+ *
+ * ### Setup
+ *
+ * #### Callback URL
+ * ```
+ * https://example.com/api/auth/callback/iracing
+ * ```
+ *
+ * #### Configuration
+ * ```ts
+ * import { Auth } from "@auth/core"
+ * import iRacing from "@auth/core/providers/iracing"
+ *
+ * const request = new Request(origin)
+ * const response = await Auth(request, {
+ *   providers: [
+ *     iRacing({
+ *       clientId: IRACING_CLIENT_ID,
+ *       clientSecret: IRACING_CLIENT_SECRET
+ *     })
+ *   ]
+ * })
+ * ```
+ *
+ * ### Resources
+ *
+ * - [iRacing OAuth documentation](https://oauth.iracing.com/oauth2/book/introduction.html)
+ *
+ * ### Notes
+ *
+ * By default, Auth.js assumes that the iRacing provider is
+ * based on the [OAuth 2](https://www.rfc-editor.org/rfc/rfc6749.html) specification.
+ *
+ * You need to configure a client with iRacing as described at https://oauth.iracing.com/oauth2/book/client_registration.html
+ *
+ * :::tip
+ *
+ * The HubSpot provider comes with a [default configuration](https://github.com/nextauthjs/next-auth/blob/main/packages/core/src/providers/hubspot.ts).
+ * To override the defaults for your use case, check out [customizing a built-in OAuth provider](https://authjs.dev/guides/configuring-oauth-providers).
+ *
+ * :::
+ *
+ * :::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).
