Update README.md

[Pomax]

this does not need to be installed globally.

I find it particularly useful to use it this way:

timeout -s SIGUSR1 3m node -r why-is-node-running/include myscript.js

could be also added to readme. This just tells you what's wrong if the program is stuck after 3m of operation.

probably something you'll want to write your own PR for, so that @mafintosh can make decisions and leave comments on them separately.

Done in #63

Thanks for the PR. I've updated the installation options to reflect global installation as an optional choice under #74, so I will close this one.

@jonkoops cheers. Small note: the use of short flags is pretty universal, so telling folks to use -D or -g is nicer than the rather verbose full name flags with extra dashes.

Thanks for the feedback, but I disagree. You never know the skill level of the person installing your packages, so it's best to assume that they don't know the meaning of any of these shorthands. Giving them the more verbose version adds extra clarity, and for those that already know the commands there isn't really that much contextual overhead. I'd rather be a bit more verbose here if that means it is inclusive.
