 For URL parameters and matrix parameters, you can add a constraint in the form of a regular expression.
 Note that back slashes have to be escaped.

 ## Optional trailing slashes
 
 `.test(path, options)` accepts an option object:
-- `trailingSlash`: if truthy, it will make trailing slashes optional (default to `true`).
+- `strictTrailingSlash`: whether or not trailing slashes are optional (default to `false`).
 
 ```javascript
 var path = new Path('/my-path');
 
-path.test('/my-path/')       // => null

+## Query parameters
+
+Query parameters are handled by [search-params](https://github.com/rcs/search-params). `test`, `partialTest` and `build` accept [search-params options](https://github.com/troch/search-params#options).
+
+```js
+path.build(params, {
+    queryParams: {
+        arrayFormat: 'index',
+        booleanFormat: 'none'
+    }
+});
