+# OpenTelemetry AWS Lambda Instrumentation for Node.js
+
+[![NPM Published Version][npm-img]][npm-url]
+[![dependencies][dependencies-image]][dependencies-url]
+[![devDependencies][devDependencies-image]][devDependencies-url]
+[![Apache License][license-image]][license-image]
+
+This module provides automatic instrumentation for [`AWS Lambda`](https://docs.aws.amazon.com/lambda/latest/dg/nodejs-handler.html).
+
+This module is currently under active development and not ready for general use.
+
+## Installation
+
+```bash
+npm install --save @opentelemetry/instrumentation-aws-lambda
+```
+
+## Usage
+
+Create a file to initialize the instrumentation, such as `lambda-wrapper.js`.
+```js
+const { NodeTracerProvider } = require('@opentelemetry/node');
+const { AwsLambdaInstrumentation } = require('@opentelemetry/instrumentation-aws-lambda');
+const { registerInstrumentations } = require('@opentelemetry/instrumentation');
+
+const provider = new NodeTracerProvider();
+provider.register();
+
+registerInstrumentations({
+ instrumentations: [
+ new AwsLambdaInstrumentation()
+ ],
+ tracerProvider: provider,
+});
+```
+
+In your Lambda function configuration, add or update the `NODE_OPTIONS` environment variable to require the wrapper, e.g.,
+
+`NODE_OPTIONS=--require lambda-wrapper`
