+**INFO**: You can also _provide other contexts_ for all available functions. This allows you to manipulate data from another opened windows (like `nw.js` Window.open function).
+
+Example: <code>
+// Import module and create context variable
+import * as TMS from './TMS';
+var context;
+
+// Open window
+nw.Window.open('project/somePage.html', {}, function(data:any){
+	context = data.window.document;
+});
+
+// Set div CSS data from new opened window by providing context
+TMS.css('someDivInsideNewWindow', { 'width': '100%', height: '20px' }, context);
+</code>
