 ### Prerequisites
 
-This SDK uses Node.js and we support the Active LTS and Current releases, as defined by
-[this table](https://github.com/nodejs/Release#release-schedule).  We support both [NPM](https://npmjs.org) and
-[Yarn](https://yarnpkg.com/lang/en/docs/install/) for package management.
+This SDK uses Node.js and we support any of the
+[Current, Active and Maintenance LTS versions](https://nodejs.org/en/about/releases/). We support both
+[NPM](https://npmjs.org) and [Yarn](https://yarnpkg.com/lang/en/docs/install/) for package management.
 
 At the moment, we only support building on macOS and Linux, where standard GNU tools like `make` are available.
 
 ### Make Targets
 
-The first time you build, run `make ensure` to install and prepare native plugins for V8:
-
-    $ make ensure
-
-This is only necessary if you intend to produce a build that is capable of running older versions of the SDK
-contained in this directory.  If you do intend to do this, you must have node `6.10.2` installed.
-
 To build the SDK, simply run `make` from the root directory (where this `README` lives, at `sdk/nodejs/` from the repo's
 root).  This will build the code, run tests, and install the package and its supporting artifacts.
