+In case you are using a global catch-all exception filter (which is either a filter registered with
+`app.useGlobalFilters()` or a filter registered in your app module providers annotated with a `@Catch()` decorator
+without arguments), add a `@WithSentry()` decorator to the `catch()` method of this global error filter. This decorator
+will report all unexpected errors that are received by your global error filter to Sentry:
+
+```javascript {2, 6}
+import { Catch, ExceptionFilter } from '@nestjs/common';
+import { WithSentry } from '@sentry/nestjs';
+
+@Catch()
+export class YourCatchAllExceptionFilter implements ExceptionFilter {
+  @WithSentry()
+  catch(exception, host): void {
+    // your implementation here
+  }
+}
+```
+
+In case you do not have a global catch-all exception filter, add the `SentryGlobalFilter` to the providers of your main
+module. This filter will report all unhandled errors to Sentry that are not caught by any other error filter.
+**Important:** The `SentryGlobalFilter` needs to be registered before any other exception filters.
+
+```javascript {3, 9}
+import { Module } from '@nestjs/common';
+import { APP_FILTER } from '@nestjs/core';
+import { SentryGlobalFilter } from '@sentry/nestjs/setup';
+
+@Module({
+  providers: [
+    {
+      provide: APP_FILTER,
+      useClass: SentryGlobalFilter,
+    },
+    // ..other providers
+  ],
+})
+export class AppModule {}
+```

 By default, exceptions with status code 4xx are not sent to Sentry. If you still want to capture these exceptions, you can do so manually with `Sentry.captureException()`:
