Be more explicit in doc/api/synopsis.md

• Version: master
• Subsystem: docs

Based on nodejs/help#1049 raised by @the-wazz

doc/api/synopsis.md contains the following text:

To run the server, put the code into a file called example.js and execute
it with Node.js:

$ node example.js
Server running at http://127.0.0.1:3000/

Many of the examples in the documentation can be run similarly.

It would be good if this section could assume less knowledge on the part of the reader.

Useful resources

• Vague doc help#1049 goes into some detail about the things that may be unclear
• https://stackoverflow.com/questions/6737824/how-to-run-a-hello-js-file-in-node-js-on-windows has a good breakdown
• The first and second sections of the Rust Book also cover a lot of the same ground.

If anyone would like to pick this up feel free.

Is this claimed yet? Could I please work on it as my first contribution?

[timotew]

@Aseged It's claimed. http://nodetodo.org/ can be very useful for getting a first PR.

@timotew Thanks for the link :-)

Sorry, forgot to remove the good-first-issue label after @timotew picked it up.
