 ## Add a rule to an existing Style Sheet
 
-`sheet.addRule([name], style, [options])`
+`sheet.addRule(nameOrSelector, style, [options])`
 
 This function will use [insertRule](https://developer.mozilla.org/en-US/docs/Web/API/CSSStyleSheet/insertRule) API if your Style Sheet is already attached to the DOM. In this case **you will not see this CSS Rule in the "Elements" view of the dev tools**. You can always verify correct rendering by using the selector on some DOM Node and watch styles applied as well as in the "Styles" inspector.
 
 If you use `addRule()` before you call `attach()`, styles will be rendered in one batch using `textContent` API which will not have the above-described side effect.
 
+## Replace a rule in an existing Style Sheet
+
+`sheet.replaceRule(nameOrSelector, style, [options])`
+
+Same as `sheet.addRule(...)` but replaces a rule with the same name if found.
+
 ### Options
 
 - `index` - index where the rule should be added, by default, rules get pushed at the end.
