+### dotInIgnore
+
+This rule allows ignore patterns to match filenames starting with a period.
+For example, if the `ignore` option contains `"http://example.com/**"` and the `dotInIgnore` option is set to `true`, paths containing filenames that start with `.` (like `"http://example.com/.hidden/index.html"`) will be ignored.
+You can disable this behavior by setting `dotInIgnore` to `false`.

 ### preferGET
 
 An array of [origins](https://url.spec.whatwg.org/#origin) to lets the rule connect to the origin's URL by `GET` instead of default `HEAD` request.
