Guide to creating a new linter

[basarat]

As I understand from the samples there are two things that one needs to do:

1.)
in package.json :

 "linter-package": true,

2.)
and then have a file called lib/your-package-name and export something that inherits from http://atomlinter.github.io/Linter/

3.)
Optionally you can redirect to a separate file lib/something by having "linter-implementation": "something", in your package.json

Is my understanding correct?
