 Include `kothic.js` from the `dist` directory on your page. Now you can call:
 
 ```javascript
-var kothic = new Kothic({
-            buffered: false,  // (optional) if true, result will appear only after all layers are rendered
-            styles: ['osmosnimki-maps', 'surface'], // (optional) only specified styles will be rendered, if any
-            locales: ['be', 'ru', 'en'] // (optional) map languages, see below
-        });
-```
-
-`locales` Kothic-JS supports map localization based on name:*lang* tags. Renderer will check all mentioned languages in order of persence.  If object doesn't have localized name, *name* tag will be used.

-Tile rendering:
-
-```javascript
-kothic.render(
+Kothic.render(
 	canvas, // canvas element (or its id) to render on
 	data, // JSON data to render
 	zoom, // zoom level
-	onRenderComplete, // (optional) callback to call when rendering is done
-	);
+	{
+		onRenderComplete: callback, // (optional) callback to call when rendering is done

+    	locales: ['be', 'ru', 'en'] // (optional) map languages, see below
+	});
 ```
 
-Note: you should new renderer instance for any tile you want to render since Kothic has unsolved concurrency issues.
