-## Supported Node.js Versions
-
-Our client libraries follow the [Node.js release schedule](https://nodejs.org/en/about/releases/).
-Libraries are compatible with all current _active_ and _maintenance_ versions of
-Node.js.
-
-Client libraries targetting some end-of-life versions of Node.js are available, and
-can be installed via npm [dist-tags](https://docs.npmjs.com/cli/dist-tag).
-The dist-tags follow the naming convention `legacy-(version)`.
-
-_Legacy Node.js versions are supported as a best effort:_
-
-* Legacy versions will not be tested in continuous integration.
-* Some security patches may not be able to be backported.
-* Dependencies will not be kept up-to-date, and features will not be backported.
-
-#### Legacy tags available
-
-* `legacy-8`: install client libraries from this dist-tag for versions
-  compatible with Node.js 8.
-
 ## Versioning
 
 This library follows [Semantic Versioning](http://semver.org/).
