+## 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/sql@legacy-8` installs client libraries
+for versions compatible with Node.js 8.
+
+## Versioning
+
+This library follows [Semantic Versioning](http://semver.org/).
+
+More Information: [Google Cloud Platform Launch Stages][launch_stages]
+
+[launch_stages]: https://cloud.google.com/terms/launch-stages

+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when

+   * @param {string} [options.projectId] - The project ID from the Google
+   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check

+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when

+   * The options accepted by the constructor are described in detail
+   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
+   * The common options are:
+   * @param {object} [options.credentials] - Credentials object.
+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when
+   *     using a .pem or .p12 keyFilename.
+   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
+   *     .p12 key downloaded from the Google Developers Console. If you provide
+   *     a path to a JSON file, the projectId option below is not necessary.
+   *     NOTE: .pem and .p12 require you to specify options.email as well.
+   * @param {number} [options.port] - The port on which to connect to
+   *     the remote host.
+   * @param {string} [options.projectId] - The project ID from the Google
+   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
+   *     the environment variable GCLOUD_PROJECT for your project ID. If your

+   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
+   *     your project ID will be detected automatically.
+   * @param {string} [options.apiEndpoint] - The domain name of the
+   *     API remote host.
+   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
+   *     Follows the structure of {@link gapicConfig}.

+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when

+   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
+   *     .p12 key downloaded from the Google Developers Console. If you provide
+   *     a path to a JSON file, the projectId option below is not necessary.
+   *     NOTE: .pem and .p12 require you to specify options.email as well.

+   *     the remote host.
+   * @param {string} [options.projectId] - The project ID from the Google
+   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check

+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when

+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when

+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when

+   * @param {string} [options.projectId] - The project ID from the Google

+   * @param {string} [options.credentials.client_email]
+   * @param {string} [options.credentials.private_key]
+   * @param {string} [options.email] - Account email address. Required when

+   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
+   *     .p12 key downloaded from the Google Developers Console. If you provide
+   *     a path to a JSON file, the projectId option below is not necessary.
+   *     NOTE: .pem and .p12 require you to specify options.email as well.
+   * @param {number} [options.port] - The port on which to connect to
+   *     the remote host.
+   * @param {string} [options.projectId] - The project ID from the Google
+   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
+   *     the environment variable GCLOUD_PROJECT for your project ID. If your

-## 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/sql@legacy-8` installs client libraries
-for versions compatible with Node.js 8.
-
-## Versioning

-   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
-   * The common options are:
-   * @param {object} [options.credentials] - Credentials object.
-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when
-   *     using a .pem or .p12 keyFilename.
-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
-   *     the environment variable GCLOUD_PROJECT for your project ID. If your
-   *     app is running in an environment which supports
-   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
-   *     your project ID will be detected automatically.
-   * @param {string} [options.apiEndpoint] - The domain name of the
-   *     API remote host.
-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.
-   * @param {boolean} [options.fallback] - Use HTTP/1.1 REST mode.
-   *     For more information, please check the
-   *     {@link https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#http11-rest-api-mode documentation}.

-   * Construct an instance of SqlBackupRunsServiceClient.
-   *
-   * @param {object} [options] - The configuration object.
-   * The options accepted by the constructor are described in detail
-   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
-   * The common options are:
-   * @param {object} [options.credentials] - Credentials object.
-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when
-   *     using a .pem or .p12 keyFilename.
-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
-   *     the environment variable GCLOUD_PROJECT for your project ID. If your
-   *     app is running in an environment which supports
-   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
-   *     your project ID will be detected automatically.
-   * @param {string} [options.apiEndpoint] - The domain name of the
-   *     API remote host.
-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.
-   * @param {boolean} [options.fallback] - Use HTTP/1.1 REST mode.
-   *     For more information, please check the
-   *     {@link https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#http11-rest-api-mode documentation}.

-   *     need to avoid loading the default gRPC version and want to use the fallback
-   *     HTTP implementation. Load only fallback version and pass it to the constructor:

-   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
-   * The common options are:
-   * @param {object} [options.credentials] - Credentials object.
-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when
-   *     using a .pem or .p12 keyFilename.
-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
-   *     the environment variable GCLOUD_PROJECT for your project ID. If your

-   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
-   *     your project ID will be detected automatically.

-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.
-   * @param {boolean} [options.fallback] - Use HTTP/1.1 REST mode.
-   *     For more information, please check the
-   *     {@link https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#http11-rest-api-mode documentation}.

-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when

-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check

-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.

-   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
-   * The common options are:
-   * @param {object} [options.credentials] - Credentials object.
-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when
-   *     using a .pem or .p12 keyFilename.
-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
-   *     the environment variable GCLOUD_PROJECT for your project ID. If your

-   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
-   *     your project ID will be detected automatically.

-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.

-   * The options accepted by the constructor are described in detail
-   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
-   * The common options are:
-   * @param {object} [options.credentials] - Credentials object.
-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when
-   *     using a .pem or .p12 keyFilename.
-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
-   *     the environment variable GCLOUD_PROJECT for your project ID. If your
-   *     app is running in an environment which supports
-   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
-   *     your project ID will be detected automatically.
-   * @param {string} [options.apiEndpoint] - The domain name of the
-   *     API remote host.
-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.
-   * @param {boolean} [options.fallback] - Use HTTP/1.1 REST mode.
-   *     For more information, please check the
-   *     {@link https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#http11-rest-api-mode documentation}.
-   * @param {gax} [gaxInstance]: loaded instance of `google-gax`. Useful if you
-   *     need to avoid loading the default gRPC version and want to use the fallback
-   *     HTTP implementation. Load only fallback version and pass it to the constructor:

-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check

-   * The options accepted by the constructor are described in detail
-   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
-   * The common options are:
-   * @param {object} [options.credentials] - Credentials object.
-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when
-   *     using a .pem or .p12 keyFilename.
-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
-   *     the environment variable GCLOUD_PROJECT for your project ID. If your

-   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
-   *     your project ID will be detected automatically.
-   * @param {string} [options.apiEndpoint] - The domain name of the
-   *     API remote host.
-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.
-   * @param {boolean} [options.fallback] - Use HTTP/1.1 REST mode.
-   *     For more information, please check the
-   *     {@link https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#http11-rest-api-mode documentation}.

-   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
-   * The common options are:
-   * @param {object} [options.credentials] - Credentials object.
-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when
-   *     using a .pem or .p12 keyFilename.
-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
-   *     the environment variable GCLOUD_PROJECT for your project ID. If your

-   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
-   *     your project ID will be detected automatically.

-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.

-   *     For more information, please check the
-   *     {@link https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#http11-rest-api-mode documentation}.

-   * @param {object} [options] - The configuration object.
-   * The options accepted by the constructor are described in detail
-   * in [this document](https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#creating-the-client-instance).
-   * The common options are:
-   * @param {object} [options.credentials] - Credentials object.
-   * @param {string} [options.credentials.client_email]
-   * @param {string} [options.credentials.private_key]
-   * @param {string} [options.email] - Account email address. Required when
-   *     using a .pem or .p12 keyFilename.
-   * @param {string} [options.keyFilename] - Full path to the a .json, .pem, or
-   *     .p12 key downloaded from the Google Developers Console. If you provide
-   *     a path to a JSON file, the projectId option below is not necessary.
-   *     NOTE: .pem and .p12 require you to specify options.email as well.
-   * @param {number} [options.port] - The port on which to connect to
-   *     the remote host.
-   * @param {string} [options.projectId] - The project ID from the Google
-   *     Developer's Console, e.g. 'grape-spaceship-123'. We will also check
-   *     the environment variable GCLOUD_PROJECT for your project ID. If your
-   *     app is running in an environment which supports
-   *     {@link https://cloud.google.com/docs/authentication/application-default-credentials Application Default Credentials},
-   *     your project ID will be detected automatically.
-   * @param {string} [options.apiEndpoint] - The domain name of the
-   *     API remote host.
-   * @param {gax.ClientConfig} [options.clientConfig] - Client configuration override.
-   *     Follows the structure of {@link gapicConfig}.
-   * @param {boolean} [options.fallback] - Use HTTP/1.1 REST mode.
-   *     For more information, please check the
-   *     {@link https://github.com/googleapis/gax-nodejs/blob/main/client-libraries.md#http11-rest-api-mode documentation}.
