-![功能介绍](images/introduction-CN.png)
-
-## 3 技术优势
-
-ElasticPDF 延续了 pdf.js-dist 的架构风格，全部使用朴素 Javascript 代码开发，简单来说 是在 pdf.js-dist 代码包中增加了几个 js 文件，无需任何在线依赖即可运行， 因而非常适合作为功能模块整合到其他项目中。
-
-不仅可以部署于公网环境应用，独立、简洁的特点也让其拥有完全透明和可控的安全性，因而被选择**部署于众多内网系统**中。
-
-经过多年的研发，**即使是只依赖 HTML，CSS 和 Javascript 运行的产品，批注等功能的产品力也已接近世界一流的PDF编辑器（比如 Adobe Acrobat）**，具体为批注可以以标准格式写入pdf中，包括注释的任意语言的文字，之后可以再在其他编辑器中编辑。
-
-另外还可以将 **批注独立导出为 JSON** 格式，便于入库和重载回显，在云端协同的系统中非常便利和经济，因为只需要一个在线原文档和保存数量级通常不到 1M 的批注文件，而不再需要把批注合并到文档中一起保存到后端数据库，可以节省很多流量、宽带和储存费用。

-ElasticPDF is a **new professional PDF editor development library**, based on the open source pdf.js-dist, with added annotation features, supporting full offline deploy, and suitable for public and intranet systems. The code structure continues the simple style of pdf.js-dist, is compatible with all mainstream browsers, and can be deployed not only in Web projects, but also embedded in any desktop and mobile projects.
- 
-## 0 Usage
-After purchasing a license, we will provide a **out-of-the-box** offline code package. The installation and deployment method is the same as the **pdf.js-dist** code package. The specific method is to use components such as **`<iframe>`** or **`<webview>`** to import the _**`viewer.html`**_ in the code package to complete the embedding without downloading any dependencies.

+## 3 技术优势
 
-ElasticPDF continues the architectural style of pdf.js-dist, and is developed entirely with simple Javascript code. In short, it adds several js files to the pdf.js-dist code package, and can run without any online dependencies, so it is very suitable for integration into other projects as a functional module.
+ElasticPDF 延续了 pdf.js-dist 的架构风格，全部使用朴素 Javascript 代码开发，简单来说 是在 pdf.js-dist 代码包中增加了几个 js 文件，无需任何在线依赖即可运行， 因而非常适合作为功能模块整合到其他项目中。
 
-It not only can it be deployed in public network environment applications, but its independent and simple features also give it completely transparent and controllable security, so it is chosen to be **deployed in many intranet systems**.
+不仅可以部署于公网环境应用，独立、简洁的特点也让其拥有完全透明和可控的安全性，因而被选择**部署于众多内网系统**中。
 
-After years of research and development, **even if it is a product that only relies on HTML, CSS and Javascript to run, the product power of annotation and other features is close to that of world-class PDF editors (such as Adobe Acrobat)**. Specifically, annotations can be written into PDF in a standard format, including text in any language of the annotation comment, and can be edited in other editors later.
+经过多年的研发，**即使是只依赖 HTML，CSS 和 Javascript 运行的产品，批注等功能的产品力也已接近世界一流的PDF编辑器（比如 Adobe Acrobat）**，具体为批注可以以标准格式写入pdf中，包括注释的任意语言的文字，之后可以再在其他编辑器中编辑。
 
-In addition, **annotations can be exported independently in JSON** format, which is convenient for storage and reload echo. It is very convenient and economical in cloud-based collaborative systems, because only an online original document and an annotation file with a size of usually less than 1M are required, and there is no need to merge the annotations into the document and save them together in the back-end database, which can save a lot of traffic, broadband and storage costs.
+另外还可以将 **批注独立导出为 JSON** 格式，便于入库和重载回显，在云端协同的系统中非常便利和经济，因为只需要一个在线原文档和保存数量级通常不到 1M 的批注文件，而不再需要把批注合并到文档中一起保存到后端数据库，可以节省很多流量、宽带和储存费用。
