 ## Query update
 
-Updates URL string with new query params<br />
+Updates URL query with new query parameters<br />
 
 Has **2** signatures:
 - Receives **2** parameters, to change one query paramenter:
     - **key** - **String**. Paramenter key
     - **value** - **String**. Paramenter value
 - Receives **1** parameter, to change multiple parameters:
-    - **paramenters** - **Object** where key is parameter key and value is paramenter value
+    - **paramenters** - **Object** where **key** is parameter key and **value** is paramenter value
