+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS

+# OpenTelemetry SDK for Node.js
+
+[![Gitter chat][gitter-image]][gitter-url]
+[![NPM Published Version][npm-img]][npm-url]
+[![dependencies][dependencies-image]][dependencies-url]
+[![devDependencies][devDependencies-image]][devDependencies-url]
+[![Apache License][license-image]][license-image]
+
+This package provides the full OpenTelemetry SDK for Node.js including tracing and metrics.
+
+## Quick Start
+
+To get started you need to install `@opentelemetry/sdk-node`, a metrics and/or tracing exporter, and any appropriate plugins for the node modules used by your application.
+
+### Installation
+
+```sh
+$ # Install the SDK
+$ npm install @opentelemetry/sdk-node
+
+$ # Install exporters and plugins
+$ npm install \
+    @opentelemetry/exporter-jaeger \ # add tracing exporters as needed
+    @opentelemetry/exporter-prometheus # add metrics exporters as needed
+    @opentelemetry/plugin-http # add plugins as needed
+
+$ # or install all officially supported core and contrib plugins
+$ npm install @opentelemetry/plugins-node-all
+```
+
+> Note: this example is for Node.js. See [examples/tracer-web](https://github.com/open-telemetry/opentelemetry-js/tree/master/examples/tracer-web) for a browser example.
+
+### Initialize the SDK
+
+Before any other module in your application is loaded, you must initialize the SDK.
+If you fail to initialize the SDK or initialize it too late, no-op implementations will be provided to any library which acquires a tracer or meter from the API.
+This example uses Jaeger and Prometheus, but exporters exist for [other tracing backends][other-tracing-backends].
+
+```javascript
+const opentelemetry = require("@opentelemetry/sdk-node");
+const { JaegerExporter } = require("@opentelemetry/exporter-jaeger");
+const { PrometheusExporter } = require("@opentelemetry/exporter-prometheus");
+
+const jaegerExporter = new JaegerExporter({
+  serviceName: 'my-service',
+});
+const prometheusExporter = new PrometheusExporter({ startServer: true });
+
+const sdk = new opentelemetry.NodeSDK({
+  // Optional - if omitted, the tracing SDK will not be initialized
+  traceExporter: jaegerExporter,
+  // Optional - If omitted, the metrics SDK will not be initialized
+  metricExporter: prometheusExporter,
+
+  // See the Configuration section below for additional  configuration options
+});
+
+// You can optionally detect resources asynchronously from the environment.
+// Detected resources are merged with the resources provided in the SDK configuration.
+sdk
+  .autoDetectResources()
+  .then(() => {
+    sdk.start();
+  })
+```
+
+## Configuration
+
+Below is a full list of configuration options which may be passed into the `NodeSDK` constructor;
+
+### contextManager
+
+Use a custom context manager. Default: [AsyncHooksContextManager](../opentelemetry-context-async-hooks/README.md)
+
+### httpTextPropagator
+
+Use a custom propagator. Default: [CompositePropagator](../opentelemetry-core/src/context/propagation/composite.ts) using [W3C Trace Context](../opentelemetry-core/README.md#httptracecontext-propagator) and [Correlation Context](../opentelemetry-core/README.md#correlation-context-propagator)
+
+### logger
+
+Use a custom logger. Default: Logging disabled
+
+### logLevel
+
+Default: [INFO](../opentelemetry-core/src/common/types.ts#L19)
+
+### metricBatcher
+
+Use a custom batcher for metrics. Default: [UngroupedBatcher](../opentelemetry-metrics/src/export/Batcher.ts#L50)
+
+### metricExporter
+
+Configure a metric exporter. If an exporter is not configured, the metrics SDK will not be initialized and registered.
+
+### metricInterval
+
+Configure an interval for metrics export in ms. Default: 60,000 (60 seconds)
+
+### plugins
+
+Configure plugins. By default, all plugins which are installed and in the [Default Plugins List](../opentelemetry-node/src/config.ts#L29) will be enabled.
+
+### resource
+
+Configure a resource. Resources may also be detected by using the `autoDetectResources` method of the SDK.
+
+### sampler
+
+Configure a custom sampler. By default all traces will be sampled.
+
+### spanProcessor
+
+### traceExporter
+
+Configure a trace exporter. If an exporter OR span processor is not configured, the tracing SDK will not be initialized and registered. If an exporter is configured, it will be used with a [BatchSpanProcessor](../opentelemetry-tracing/src/export/BatchSpanProcessor.ts).
+
+### traceParams
+
+Configure tracing parameters. These are the same trace parameters used to [configure a tracer](../opentelemetry-tracing/src/types.ts#L71).
