 ### Prerequisites
 
 Ensure the SDK supports all of the platforms you're targeting. In particular, the SDK targets any ES5-compliant JavaScript environment. We officially support:
-- Node.js >= 4.0.0. By extension, environments like AWS Lambda, Google Cloud Functions, and Auth0 Webtasks are supported as well. Older Node.js releases likely work too (try `npm test` to validate for yourself), but are not formally supported.
+- Node.js >= 8.0.0. By extension, environments like AWS Lambda, Google Cloud Functions, and Auth0 Webtasks are supported as well. Older Node.js releases likely work too (try `npm test` to validate for yourself), but are not formally supported.
 - [Web browsers](https://caniuse.com/#feat=es5)
 
 Other environments likely are compatible, too, but note that we don't officially support them:
