+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,

+      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
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          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 Logs SDK
+
+[![NPM Published Version][npm-img]][npm-url]
+[![Apache License][license-image]][license-image]
+
+**Note: This is an experimental package under active development. New releases may include breaking changes.**
+
+OpenTelemetry logs module contains the foundation for all logs SDKs 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 logs for client-side JavaScript (browser) and Node.js.
+
+It does **not** provide automated instrumentation of known libraries or host environment logs out-of-the-box.
+
+## Installation
+
+```bash
+npm install --save @opentelemetry/api-logs
+npm install --save @opentelemetry/sdk-logs
+```
+
+## Usage
+
+The basic setup of the SDK can be seen as followings:
+
+```js
+const logsAPI = require("@opentelemetry/api-logs");
+const {
+  LoggerProvider,
+  SimpleLogRecordProcessor,
+  ConsoleLogRecordExporter,
+} = require("@opentelemetry/sdk-logs");
+
+// To start a logger, you first need to initialize the Logger provider.
+const loggerProvider = new LoggerProvider();
+// Add a processor to export log record
+loggerProvider.addLogRecordProcessor(
+  new SimpleLogRecordProcessor(new ConsoleLogRecordExporter())
+);
+
+//  To create a log record, you first need to get a Logger instance
+const logger = loggerProvider.getLogger("default");
+
+// You can also use global singleton
+logsAPI.logs.setGlobalLoggerProvider(loggerProvider);
+const logger = logsAPI.logs.getLogger("default");
+
+// logging an event in an instrumentation library
+logger
+  .getLogEvent("event-name", {
+    severityNumber: SeverityNumber.WARN,
+    severityText: "WARN",
+    body: "this is a log event body",
+    attributes: { "log.type": "LogEvent" },
+  })
+  .emit();
+
+// logging an event in a log appender
+logger
+  .getLogRecord({
+    severityNumber: SeverityNumber.INFO,
+    severityText: "INFO",
+    body: "this is a log record body",
+    attributes: { "log.type": "LogRecord" },
+  })
+  .emit();
+```
+
+## Config
+
+Logs configuration is a merge of user supplied configuration with both the default
+configuration as specified in [config.ts](./src/config.ts)
+
+## Example
+
+See [examples/logs](https://github.com/open-telemetry/opentelemetry-js/tree/main/experimental/examples/logs)
