Get help on npm.
npm help <term> [<terms..>]
If supplied a topic, then show the appropriate documentation page.
If the topic does not exist, or if multiple terms are provided, then run the help-search command to find a match. Note that, if help-search finds a single subject, then it will run help on that topic, so unique matches are equivalent to specifying a topic name.
The program to use to view help content.
Set to "browser" to view html help content in the default web browser.
