-## SDK Status
+The official Sentry SDK for monitoring Astro applications.
 
 This SDK is in Beta and not yet fully stable. If you have feedback or encounter any bugs, feel free to
 [open an issue](https://github.com/getsentry/sentry-javascript/issues/new/choose).
 
-## General
-
-This package is a wrapper around `@sentry/node` for the server and `@sentry/browser` for the client side.
-
-## Installation and Setup
-
-Install the Sentry Astro SDK with the `astro` CLI:
-
-```bash
-npx astro add @sentry/astro
-```
-
-### Build-time Configuration
-
-Register the Sentry integration in your `astro.config.mjs`. This is where you configure build-time options such as
-source maps upload (`org`, `project`, `authToken`). Runtime SDK options (`dsn`, `environment`, `tracesSampleRate`, Replay
-sample rates, and so on) belong in dedicated init files, not on `sentry()`.
-
-```javascript
-import { defineConfig } from 'astro/config';
-import sentry from '@sentry/astro';
-
-export default defineConfig({
-  integrations: [
-    sentry({
-      org: 'your-org-slug',
-      project: 'your-sentry-project-slug',
-      authToken: process.env.SENTRY_AUTH_TOKEN,
-    }),
-  ],
-});
-```
-
-Follow [this guide](https://docs.sentry.io/product/accounts/auth-tokens/#organization-auth-tokens) to create an auth
-token and add it to your environment variables:
-
-```bash
-SENTRY_AUTH_TOKEN="your-token"
-```
-
-### Runtime SDK Configuration
-
-If you do not add `sentry.client.config.ts` or `sentry.server.config.ts`, Sentry still initializes with default options
-and reads the DSN from `PUBLIC_SENTRY_DSN`. Add those files at the project root when you want to customize client or
-server options, and pass them to `Sentry.init()`.
-
-Set `PUBLIC_SENTRY_DSN` in your environment (for example in `.env`):
-
-```bash
-PUBLIC_SENTRY_DSN="__DSN__"
-```
-
-```javascript
-// sentry.client.config.ts
-import * as Sentry from '@sentry/astro';
-
-Sentry.init({
-  dsn: '__DSN__',
-  tracesSampleRate: 1.0,
-  integrations: [Sentry.replayIntegration()],
-  replaysSessionSampleRate: 0.1,
-  replaysOnErrorSampleRate: 1.0,
-});
-```
-
-```javascript
-// sentry.server.config.ts
-import * as Sentry from '@sentry/astro';
-
-Sentry.init({
-  dsn: '__DSN__',
-  tracesSampleRate: 1.0,
-});
-```
-
-### Server Instrumentation
-
-For Astro apps configured for (hybrid) Server Side Rendering (SSR), the Sentry integration will automatically add
-middleware to your server to instrument incoming requests.
-
-The Sentry middleware enhances the data collected by Sentry on the server side by:
-
-- Enabling distributed tracing between client and server
-- Collecting performance spans for incoming requests
-- Enhancing captured errors with additional information
-
-#### Disable Automatic Server Instrumentation
-
-You can opt out of using the automatic sentry server instrumentation in your `astro.config.mjs` file:
-
-```javascript
-import { defineConfig } from 'astro/config';
-import sentry from '@sentry/astro';
-
-export default defineConfig({
-  integrations: [
-    sentry({
-      autoInstrumentation: {
-        requestHandler: false,
-      },
-    }),
-  ],
-});
-```
-
-If you opt out but still want the middleware, add it manually to your `src/middleware.js` file:
-
-```javascript
-// src/middleware.js
-import { sequence } from 'astro:middleware';
-import * as Sentry from '@sentry/astro';
-
-export const onRequest = sequence(
-  Sentry.handleRequest(),
-  // Add your other handlers after Sentry.handleRequest()
-);
-```
