-[![npm](https://img.shields.io/npm/v/grpc.svg)](https://www.npmjs.com/package/grpc)
-# Node.js gRPC Library
-
-## PREREQUISITES
-- `node`: This requires `node` to be installed, version `4.0` or above. If you instead have the `nodejs` executable on Debian, you should install the [`nodejs-legacy`](https://packages.debian.org/sid/nodejs-legacy) package.
-
-- **Note:** If you installed `node` via a package manager and the version is still less than `4.0`, try directly installing it from [nodejs.org](https://nodejs.org).
-
-## INSTALLATION
-
-Install the gRPC NPM package
-
-```sh
-npm install grpc
-```
-
-## BUILD FROM SOURCE
- 1. Clone [the grpc Git Repository](https://github.com/grpc/grpc).
- 2. Run `npm install --build-from-source` from the repository root.
-
- - **Note:** On Windows, this might fail due to [nodejs issue #4932](https://github.com/nodejs/node/issues/4932) in which case, you will see something like the following in `npm install`'s output (towards the very beginning):
-
-    ```
-     ..
-     Building the projects in this solution one at a time. To enable parallel build, please add the "/m" switch.
-     WINDOWS_BUILD_WARNING
-      "..\IMPORTANT: Due to https:\github.com\nodejs\node\issues\4932, to build this library on Windows, you must first remove C:\Users\jenkins\.node-gyp\4.4.0\include\node\openssl"
-      ...
-      ..
-    ```
-
-    To fix this, you will have to delete the folder `C:\Users\<username>\.node-gyp\<node_version>\include\node\openssl` and retry `npm install`
-
-
-## TESTING
-To run the test suite, simply run `npm test` in the install location.

-
-      (d) If the Work includes a "NOTICE" text file as part of its
-          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 any such Derivative Works as a whole, provided Your use,
-      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.
