How to auto-initiate ESLint in Atom using modified rules?

I'm just getting into Atom and ESLint - heck still a noob using Node and npm.

I've got a project working fine with Atom, Linter and ESLint, and I customized the rules of the "standard" config (as opposed to Google or AirBnB).

When I start a new project, however, nothing is carried over. It looks like I have to re-init ESLint, and then it asks for the config file again, which is obviously not my customized version.

How can I get ESLint to run automatically whenever Atom opens a JS file, using my custom rules?

Thanks in advance and let me know if my terminology is off...
