+Type: `Object` mapping `String` to `Boolean | "error" | "warning" | Object`

 Configures the rules to use.

 Object keys are rule names/aliases; object values are the rule's configuration.
 The value `false` disables a rule. The values `true` or `"error"` enable a rule
-in its default configuration and report violations as errors. Passing an object
-enables and customizes the rule. The special `default` rule assigns the default
-for all rules. Using a tag name (e.g., `whitespace`) and a setting of `false`,
-`true`, or `"error"` applies that setting to all rules with that tag. When no
-configuration object is passed or the optional `default` setting is not present,
-all rules are enabled.
+in its default configuration and report violations as errors. The value
+`"warning"` enables a rule in its default configuration and reports violations
+as warnings. Passing an object enables *and* customizes the rule; the properties
+`severity` (`"error" | "warning"`) and `enabled` (`false | true`) can be used in
+this context. The special `default` rule assigns the default for all rules.
+Using a tag name (e.g., `whitespace`) and a setting of `false`, `true`,
