docs(js): Review and update Nest.js Quick Start guide

 You need to require or import the `instrument.js` file before requiring any other modules in your application. This is necessary to ensure that Sentry can automatically instrument all modules in your application:
 
-<PlatformContent includePath="getting-started-use" />
+```javascript {filename: main.ts}
+// Import this first!
+import "./instrument";
+
+// Now import other modules
+import { NestFactory } from "@nestjs/core";
+import { AppModule } from "./app.module";
+
+async function bootstrap() {
+  const app = await NestFactory.create(AppModule);
+  await app.listen(3000);
+}
+
+bootstrap();
+```
+
+Afterwards, add the `SentryModule` as a root module to your main module:
+
+```javascript {filename: app.module.ts} {2, 8}
+import { Module } from "@nestjs/common";
+import { SentryModule } from "@sentry/nestjs/setup";
+import { AppController } from "./app.controller";
+import { AppService } from "./app.service";
+
+@Module({
+  imports: [
+    SentryModule.forRoot(),
+    // ...other modules
+  ],
+  controllers: [AppController],
+  providers: [AppService],
+})
+export class AppModule {}
+```
+
+If you're 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 `@SentryExceptionCaptured()` decorator to the filter's `catch()` method.
+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 { SentryExceptionCaptured } from '@sentry/nestjs';
+
+@Catch()
+export class YourCatchAllExceptionFilter implements ExceptionFilter {
+  @SentryExceptionCaptured()
+  catch(exception, host): void {
+    // your implementation here
+  }
+}
+```
+
+By default, only unhandled exceptions that are not caught by an error filter are reported to Sentry.
+`HttpException`s (including [derivatives](https://docs.nestjs.com/exception-filters#built-in-http-exceptions)) are also not captured by default because they mostly act as control flow vehicles.
+
+If you don't have a global catch-all exception filter, add the `SentryGlobalFilter` to the providers of your main module.
+This filter will report any unhandled errors that aren't caught by other error filters to Sentry.
+**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 {}
+```
+
+<Expandable title="Using Microservices?">
+
+If you are using `@nestjs/microservices` make sure to handle errors in RPC contexts correctly by providing your own `RpcExceptionFilter` (see https://docs.nestjs.com/microservices/exception-filters).
+`SentryGlobalFilter` in a [hybrid application](https://docs.nestjs.com/faq/hybrid-application) does not extend `BaseRpcExceptionFilter` since this depends on `@nestjs/microservices`.
+
+Use `Sentry.captureException(exception)` in your custom filter in case you want to send these errors to Sentry:
+
+```typescript
+import { Catch, RpcExceptionFilter, ArgumentsHost } from "@nestjs/common";
+import { Observable, throwError } from "rxjs";
+import { RpcException } from "@nestjs/microservices";
+import * as Sentry from "@sentry/nestjs";
+
+@Catch(RpcException)
+export class ExceptionFilter implements RpcExceptionFilter<RpcException> {
+  catch(exception: RpcException, host: ArgumentsHost): Observable<any> {
+    Sentry.captureException(exception); // optional
+    return throwError(() => exception.getError());
+  }
+}
+```
+
+</Expandable>
+
+If you have error filters for specific types of exceptions (for example `@Catch(HttpException)`, or any other `@Catch(...)` with arguments) and you want to capture errors caught by these filters, capture the errors in the `catch()` handler with `Sentry.captureException()`:
+
+```javascript {9}
+import { ArgumentsHost, BadRequestException, Catch } from '@nestjs/common';
+import { BaseExceptionFilter } from '@nestjs/core';
+import { ExampleException } from './example.exception';
+import * as Sentry from '@sentry/nestjs';
+
+@Catch(ExampleException)
+export class ExampleExceptionFilter extends BaseExceptionFilter {
+  catch(exception: unknown, host: ArgumentsHost) {
+    Sentry.captureException(exception);
+    return super.catch(new BadRequestException(exception.message), host)
+  }
+}
+```

+### Issues
+
+First, let's verify that Sentry captures errors and creates issues in your Sentry project. Add the following route to your application, which will call an undefined function, triggering an error that Sentry will capture:
+
 ```javascript
 @Get("/debug-sentry")
-getError() {
-  throw new Error("My first Sentry error!");
+  getError() {
+    setTimeout(() => {
+      try {
+        foo();

+      }
+    }, 99);
+  }

+### Tracing

+To test your tracing configuration, update the previous code snippet by starting a performance trace to measure the time it takes for the execution of your code:
