+> **Internal API Client**: This library (`@google-cloud/bigtable-api`) is an auto-generated, lightweight GAPIC layer designed as a dependency for the official handwritten client library. End users should install and import **[@google-cloud/bigtable](https://www.npmjs.com/package/@google-cloud/bigtable)** instead.

+
+## Quickstart
+### Before you begin
+
+1.  [Select or create a Cloud Platform project][projects].
+1.  [Enable billing for your project][billing].
+1.  [Enable the Cloud Bigtable API API][enable_api].
+1.  [Set up authentication][auth] so you can access the
+    API from your local workstation.
+### Installing the client library
+
+```bash
+npm install @google-cloud/bigtable-api
+```
+
+[//]: # "partials.body"
+
+## Samples
+
+Samples are in the [`samples/`][homepage_samples] directory. Each sample's `README.md` has instructions for running its sample.
+
+[//]: # "samples"
+
+## Supported Node.js Versions
+
+Our client libraries follow the [Node.js release schedule](https://github.com/nodejs/release#release-schedule).
+Libraries are compatible with all current _active_ and _maintenance_ versions of
+Node.js.
+If you are using an end-of-life version of Node.js, we recommend that you update
+as soon as possible to an actively supported LTS version.
+
+Google's client libraries support legacy versions of Node.js runtimes on a
+best-efforts basis with the following warnings:
+
+* Legacy versions are not tested in continuous integration.
+* Some security patches and features cannot be backported.
+* Dependencies cannot be kept up-to-date.
+
+Client libraries targeting some end-of-life versions of Node.js are available, and
+can be installed through npm [dist-tags](https://docs.npmjs.com/cli/dist-tag).
+The dist-tags follow the naming convention `legacy-(version)`.
+For example, `npm install @google-cloud/bigtable-api@legacy-8` installs client libraries
+for versions compatible with Node.js 8.
+
+## Versioning
+
+This library follows [Semantic Versioning](http://semver.org/).
