-Node version >= 6.12 is required.
+Node version 6.x or 8.x is required.
 
 Most of the packages require additional typings for external dependencies.
 You can include those by prepending the `@0x/typescript-typings` package to your [`typeRoots`](http://www.typescriptlang.org/docs/handbook/tsconfig-json.html) config.

More specifically, your local pip should resolve to the Python 3 version of pip, not a Python 2.x version.
