The link was pointing to the `WordPress-Core` ruleset, while `_s` uses the `WordPress` ruleset which encompasses more than just the core rules.
Pointing to the repo + the wiki seems more appropriate to me.
If the file is called `phpcs.xml` or `phpcs.xml.dist`, it is automatically picked up by PHPCS.
A `phpcs.xml` is given preference over a `phpcs.xml.dist` file. So renaming the file to `phpcs.xml.dist` allows for people to use the file provided by `_s` if they choose not to add their own, but also leaves people the freedom to easily overrule it.
