When using PHPCS+WPCS with the Atom linter, there is a rather strange and mostly undocumented configuration step that seems to be necessary.

The PHPCS package has a default tab width of 1. This makes PHPCS+WPCS fail it seems. Changing this setting to 4 resolves it.

Here's the issue AtomLinter/linter-phpcs#280

Setting https://cl.ly/3n063J1i1W1K (under linter-phpcs).

Would be helpful to note this in the readme for new users - I lost a lot of time trying to debug why things were failing! :)
