 ThorVG renders vector shapes on a given canvas buffer.
 
 You can initialize ThorVG engine first:

 ```cpp
 tvg::Initializer::init(tvg::CanvasEngine::Sw, 0);   //engine method, thread count

+Or you can draw pathes with dash stroking.
+
+```cpp
+auto path = tvg::Shape::gen();               //generate a path

 Next, this code snippet shows you how to draw SVG image.
+
 ```cpp
 auto picture = tvg::Picture::gen();         //generate a picture
 picture->load("tiger.svg");                 //Load SVG file.
-
 canvas->push(move(picture));                //push picture drawing command
 ```
+
 And here is the result.

 Begin rendering & finish it at a particular time.
+
 ```cpp
 canvas->draw();
 canvas->sync();
 ```
+
 Now you can acquire the rendered image in buffer memory.
 
 Lastly, terminate the engine after usage.
+
 ```cpp
 tvg::Initializer::term(tvg::CanvasEngine::Sw);
 ```
