+# Sourcemaps and Releases
+
+To generate and upload source maps of your Solid Start app use our vite bundler plugin.
+
+1. Install the Sentry vite plugin
+ 
+```bash
+# Using npm
+npm install @sentry/vite-plugin --save-dev
+
+# Using yarn
+yarn add @sentry/vite-plugin --dev
+```
+
+2. Configure the vite plugin
+ 
+To upload source maps you have to configure an auth token. Auth tokens can be passed to the plugin explicitly with the `authToken` option, with a `SENTRY_AUTH_TOKEN` environment variable, or with an `.env.sentry-build-plugin` file in the working directory when building your project. We recommend you add the auth token to your CI/CD environment as an environment variable.
+
+Learn more about configuring the plugin in our [Sentry Vite Plugin documentation](https://www.npmjs.com/package/@sentry/vite-plugin).
+
+```bash
+// .env.sentry-build-plugin
+SENTRY_AUTH_TOKEN=<your auth token>
+SENTRY_ORG=<your org>
+SENTRY_PROJECT=<your project name>
+```
+
+3. Finally, add the plugin to your `app.config.ts` file.
+
+```javascript
+import { defineConfig } from '@solidjs/start/config'
+import { sentryVitePlugin } from '@sentry/vite-plugin'
+
+export default defineConfig({
+  // rest of your config
+  // ...
+  
+  vite: {
+    build: {
+      sourcemap: true,
+    },
+    plugins: [
+      sentryVitePlugin({
+        org: process.env.SENTRY_ORG,
+        project: process.env.SENTRY_PROJECT,
+        authToken: process.env.SENTRY_AUTH_TOKEN,
+      }),
+    ],
+  },
+})
+```
