 ### Node options such as `--harmony`
 
 You can enable `--harmony` option in two ways:
-* Use `#! /usr/bin/env node --harmony` in the sub-commands scripts. (Note Windows does not support this pattern.)
-* Use the `--harmony` option when call the command, like `node --harmony examples/pm publish`. The `--harmony` option will be preserved when spawning sub-command process.
