+
+The `sentry init` command is AI-powered. It analyzes your project and generates a tailored integration, rather than applying a fixed template. Here's what it does:
+
+- **Analyzes your project** — reads project files and manifests to understand your Nuxt app structure, including monorepos. It also respects AI instruction files such as `CLAUDE.md`, `AGENTS.md`, and `.cursorrules`.
+- **Detects your framework** — identifies Nuxt and selects the `@sentry/nuxt` SDK.
+- **Fetches official Sentry docs** — uses the current Sentry documentation as the source of truth when generating integration code.
+- **Installs dependencies** — adds `@sentry/nuxt` using your project's package manager.
+- **Creates and modifies files** — sets up client-side and server-side initialization, Nuxt module configuration, and other selected features based on your project structure.
+- **Verifies the integration** — re-reads modified files after writing to confirm Sentry was integrated.
+
+For full details on what each file does, see the [Manual Setup](/platforms/javascript/guides/nuxt/manual-setup/) guide.
 
-This guide assumes that you enable all features and allow the wizard to create an example page or component. You can add or remove features at any time, but setting them up now will save you the effort of configuring them manually later.

-- Creates `sentry.(client|server).config.ts` to initialize the SDK
-- Creates or updates your `nuxt.config.ts` to add build options to add source maps upload and auto-instrumentation via Vite plugins
-- Creates `.env.sentry-build-plugin` with an auth token to upload source maps (this file is automatically added to `.gitignore`)
-- Adds an example page and route to your application to help verify your Sentry setup

 ## Verify Your Setup
 
-If you haven't tested your Sentry configuration yet, let's do it now. You can confirm that Sentry is working properly and sending data to your Sentry project by using the example page created by the installation wizard.
+The `sentry init` command checks the integration files it creates or modifies before it finishes. To confirm runtime events are reaching Sentry, start your Nuxt app, exercise the parts of your app that should send events, and then check your Sentry project.
+
+If you used the Nuxt installation wizard instead, you can also verify your setup with the example page or component it creates.
 
 <Expandable level="warning" title="The wizard created an example component instead of a page.">
 The wizard creates a `SentryErrorButton` component when it fails to add an example page to your project. This usually happens if you don't have a `app.vue` file or if that file does not contain the `NuxtPage` component.
