+# OpenTelemetry Metrics SDK
+
+[![NPM Published Version][npm-img]][npm-url]
+[![Apache License][license-image]][license-image]
+
+This module contains the Metrics SDK of [opentelemetry-js](https://github.com/open-telemetry/opentelemetry-js).
+
+Used standalone, this module provides methods for manual instrumentation of code, offering full control over recording metrics for client-side JavaScript (browser) and Node.js.
+
+It does **not** provide automated instrumentation of known libraries or host environment metrics out-of-the-box.
+
+## Installation
+
+```bash
+npm install --save @opentelemetry/api
+npm install --save @opentelemetry/sdk-metrics
+```
+
+## Usage
+
+The basic setup of the SDK can be seen as followings:
+
+```js
+const opentelemetry = require('@opentelemetry/api');
+const { MeterProvider } = require('@opentelemetry/sdk-metrics');
+
+// To create an instrument, you first need to initialize the Meter provider.
+// NOTE: The default OpenTelemetry meter provider does not record any metric instruments.
+//       Registering a working meter provider allows the API methods to record instruments.
+opentelemetry.metrics.setGlobalMeterProvider(new MeterProvider());
+
+// To record a metric event, we used the global singleton meter to create an instrument.
+const counter = opentelemetry.metrics.getMeter('default').createCounter('foo');
+
+// record a metric event.
+counter.add(1, { attributeKey: 'attribute-value' });
+```
+
+In conditions, we may need to setup an async instrument to observe costly events:
+
+```js
+// Creating an async instrument, similar to synchronous instruments
+const observableCounter = opentelemetry.metrics.getMeter('default')
+  .createObservableCounter('observable-counter');
+
+// Register a single-instrument callback to the async instrument.
+observableCounter.addCallback(async (observableResult) => {
+  // ... do async stuff
+  observableResult.observe(1, { attributeKey: 'attribute-value' });
+});
+
+// Register a multi-instrument callback and associate it with a set of async instruments.
+opentelemetry.metrics.getMeter('default')
+  .addBatchObservableCallback(batchObservableCallback, [ observableCounter ]);
+async function batchObservableCallback(batchObservableResult) {
+  // ... do async stuff
+  batchObservableResult.observe(observableCounter, 1, { attributeKey: 'attribute-value' });
+}
+```
+
+Views can be registered when instantiating a `MeterProvider`:
+
+```js
+const meterProvider = new MeterProvider({
+  views: [
+    // override the bucket boundaries on `my.histogram` to [0, 50, 100]
+    {
+      aggregation: {
+        type: AggregationType.EXPLICIT_BUCKET_HISTOGRAM,
+        options: {
+          boundaries: [0, 50, 100]
+        }
+      },
+      instrumentName: 'my.histogram'
+    },
+    // rename 'my.counter' to 'my.renamed.counter'
+    { name: 'my.renamed.counter', instrumentName: 'my.counter'}
+  ]
+})
+```
+
+## Example
+
+See [examples/prometheus](https://github.com/open-telemetry/opentelemetry-js/tree/main/experimental/examples/prometheus) for an end-to-end example, including exporting metrics.
