+
+### SVGA-Format 1.x support
+
+Both Prebuild & NPM, if you need to support SVGA-Format 1.x, add JSZip script to html.
+
+```html
+<script src="//s1.yy.com/ued_web_static/lib/jszip/3.1.4/??jszip.min.js,jszip-utils.min.js" charset="utf-8"></script>
+```
+
+## Usage
+
+### Load Animation Mannally
+
+You may create Player and Parser by yourself.
+
+1. Add Div Tag.
+
+```html
+<div id="demoCanvas" style="styles..."></div>
+```
+
+2. Load Animation
+
+```js
+var player = new SVGA.Player('#demoCanvas');
+var parser = new SVGA.Parser('#demoCanvas'); // Must Provide same selector eg:#demoCanvas IF support IE6+
+parser.load('rose_2.0.0.svga', function(videoItem) {
+    player.setVideoItem(videoItem);
+    player.startAnimation();
+})
+```
+
+### Load Animation Automatically
+
+Assign canvas element properties as below.
+
+```html
+<div src="rose_2.0.0.svga" loops="0" clearsAfterStop="true" style="styles..."></div>
+```
+
+Animation will play after Web-Page onload.
+
+### Replace Animation Images Dynamically
+
+You can replace specific image by yourself, ask your designer tell you the ImageKey.
+
+```
+player.setImage('http://yourserver.com/xxx.png', 'ImageKey');
+```
+
+### Add Text on Animation Image Dynamically
+
+You can add text on specific image, ask your designer tell you the ImageKey.
+
+```
+player.setText('Hello, World!', 'ImageKey');
+```
+
+```
+player.setText({ 
+    text: 'Hello, World!', 
+    family: 'Arial',
+    size: "24px", 
+    color: "#ffe0a4",
+    offset: {x: 0.0, y: 0.0}
+}, 'ImageKey'); // customize text styles.
+```

+## Issues
+
+### Android 4.x Breaks
+
+As known, some Android OS lack Blob support, add Blob Polyfill by yourself.
