+
+To instrument your Svelte application with Sentry, first install the `@sentry/svelte` and `@sentry/tracing` packages:
+
+```bash
+# Using yarn
+yarn add @sentry/svelte @sentry/tracing
+
+# Using npm
+npm install --save @sentry/svelte @sentry/tracing
+```
+
+Next, import and initialize initialize Sentry in your Svelte app's entry point (`main.ts/js`):
+
+```javascript
+import "./app.css";
+import App from "./App.svelte";
+
+import * as Sentry from "@sentry/svelte";
+import { BrowserTracing } from "@sentry/tracing";
+
+// Initialize the Sentry SDK here
+Sentry.init({
+  dsn: "___PUBLIC_DSN___",
+  integrations: [new BrowserTracing()],
+
+  // Set tracesSampleRate to 1.0 to capture 100%
+  // of transactions for performance monitoring.
+  // We recommend adjusting this value in production
+  tracesSampleRate: 1.0,
+});
+
+const app = new App({
+  target: document.getElementById("app"),
+});
+
+export default app;
+```
+
+The above configuration captures both error and performance data. We recommend adjusting `tracesSampleRate` in production, see [Sampling](https://docs.sentry.io/platforms/javascript/configuration/sampling/).
+
+After this step, Sentry will report any uncaught exceptions triggered by your application.
+
+You can trigger your first event from your development environment by raising an exception somewhere within your application. An example of this would be rendering a button whose `on:click` handler attempts to invoke a function that doesn't exist:
+
+```html
+// SomeComponent.svelte
+
+<button type="button" on:click="{unknownFunction}">
+  Throw error
+</button>
+```
+
+Once you've verified the SDK is initialized properly and you've sent a test event, check out our [complete Svelte docs](https://docs.sentry.io/platforms/javascript/guides/svelte/) for additional configuration instructions.
