### 什么是擴展? 擴展是小的軟件程序，可以修改和增強Chrome瀏覽器的功能。您可以使用Web技術，比如HTML，JavaScript和CSS寫出來。 Extensions have little to no user interface. For example, the image to the right shows the icon that provides the UI for the Google Mail Checker extension. Extensions bundle all their files into a single file that the user downloads and installs. This bundling means that, unlike ordinary web apps, extensions don't need to depend on content from the web. You can distribute your extension using the Chrome Developer Dashboard to publish to the Chrome Web Store. For more information, see the store developer documentation. #### How do I start?
