 ## Setup
 
-### 1. Configure Temporal connection
+The instructions here are a slimmed down version of the more complete getting started guide which
+you can find [here](https://docs.temporal.io/production-deployment/worker-deployments/serverless-workers/aws-lambda).
+
+### 1. Create a lambda function for your TypeScript worker
+
+Use either the AWS web UI or CLI to create a Node.js runtime Lambda function. Ex:
+
+```bash
+aws lambda create-function \
+  --function-name my-temporal-worker \
+  --runtime nodejs22.x \
+  --handler lib/index.handler \
+  --role arn:aws:iam::<YOUR_ACCOUNT_ID>:role/my-temporal-worker-execution \
+  --timeout 600 \
+  --memory-size 256
+```
+
+### 2. Configure Temporal connection
 
 Edit `temporal.toml` with your Temporal Cloud namespace address and credentials. In production,
 we'd recommend reading your credentials from a secret store, but to keep this example simple
 the toml file defaults to reading them from keys bundled along with the Lambda code.

 The External ID is provided by Temporal Cloud in your namespace's serverless worker

-### 3. (Optional) Enable OpenTelemetry
-
-The sample calls `applyDefaults(config)` in the handler, which registers Temporal SDK
-interceptors for tracing Workflow, Activity, and Nexus calls, and configures the Core SDK
-to export metrics via OTLP. To complete the setup, attach two ADOT Lambda layers:
-
-1. **ADOT JavaScript layer** — auto-instruments the handler and exports Node.js-side
-   traces to X-Ray. See [this page](https://aws-otel.github.io/docs/getting-started/lambda/lambda-js)
-   for the layer ARN for your region.
-2. **ADOT Collector layer** (`aws-otel-collector-amd64`) — runs the OTel Collector as a
-   Lambda extension, receiving Temporal Core SDK metrics via OTLP and forwarding them to
-   CloudWatch/X-Ray. See [this page](https://aws-otel.github.io/docs/getting-started/lambda)
-   for the layer ARN.
-
-Update `otel-collector-config.yaml` with your function name and region, then set the
-following environment variables on your Lambda:
-
-```
-AWS_LAMBDA_EXEC_WRAPPER=/opt/otel-instrument
-OPENTELEMETRY_COLLECTOR_CONFIG_URI=/var/task/otel-collector-config.yaml
-```
-
-`AWS_LAMBDA_EXEC_WRAPPER` enables the JS layer's auto-instrumentation.
-`OPENTELEMETRY_COLLECTOR_CONFIG_URI` points the collector at the custom config that
-routes metrics to CloudWatch EMF and traces to X-Ray.
+### 4. (Optional) Enable OpenTelemetry
 
-Enable X-Ray active tracing on the Lambda function (required for traces to appear):
-
-```bash
-aws lambda update-function-configuration --function-name <function-name> \
-  --tracing-config Mode=Active
-```
+If you want traces, metrics, and logs, you'll have to attach the ADOT layer to your Lambda function.
+You will need to add the appropriate layer for your runtime and region. See [this page
+](https://aws-otel.github.io/docs/getting-started/lambda#getting-started-with-aws-lambda-layers)
+for more info. See also the [Temporal docs on adding observability
+](https://docs.temporal.io/develop/typescript/workers/serverless-workers/aws-lambda#add-observability)
+for additional TypeScript-specific configuration.
 
 Then run the extra setup to grant the Lambda role the necessary permissions:
 
 ```bash
 ./extra-setup-steps <role-name> <function-name> <region> <account-id>
 ```
 
-### 4. Deploy the Lambda function
+Update `otel-collector-config.yaml` with your function name and region as needed.
 
-Create a Lambda function in AWS with:
-
-- **Runtime**: Node.js >=20
-- **Handler**: `index.handler` (the default)
-- **Architecture**: x86_64
