How to use .csslintrc in Atom's CSSLint to ignore rules?

I'm using Linter with Linter-CSSlint in Atom and I want to prevent some waings globally (like "ids").

In CSSlint's readme says that it supports .csslintrc but I can't find info of where should I put this .csslintrc file.

I saw a .csslintrc file inside:

.atom
  packages
    linter-csslint
      spec
        fixtures 
          project

with this inside: --errors=empty-rules

But adding there some rules there doesn't do anything. Rules like:

--errors=empty-rules
{
    "ids": false,
     "box-model": false,
 }

Can somebody point me in the right direction?

Thanks!
