-ZenTao is practical and pragmatic. It has full features and beautiful interfaces, and is easy to use. ZenTao is well structured and can be flexibly extended. It also has powerful search features, various forms of statistical reports and complete API.
+# Introduction
 
+ZenTao is the first opensource project management software in China. It’s a comprehensive, all-in-one platform that covers the main PM process, from product and project management to quality management, documentation management, organization management, and office management.
 
-ZenTao focuses on development project management!
+Since its establishment in 2009, ZenTao has helped tens of thousands of teams and organizations improve their project management structures. Currently, ZenTao is being used by some of the largest companies in the world, ranging from those in the sectors of finance and telecoms to manufacturing and software development. They trust ZenTao for streamlining their processes, simplifying communication between clients and employees, increasing transparency, and improving productivity and efficiency.
 
-## 2. Why is it called ZenTao?
+# Design Philosophy
 
-Zen(禅) and Tao(道) are the two Chinese characters that have rich meanings in both religion and culture. ZenTao Project Management Software takes the cultural meaning of Zen and Tao, and is expected to convey our understanding and thinking of management. Inspired by The Tao of Programming and The Zen of Programming, we named our software ZenTao.
+The name ZenTao came from combining two Chinese characters, Zen(禅) and Tao(道), which have rich inspirations pertaining to culture and history. With its name referring to highly respected aspects of life, it’s only logical to convey their meaning in management by providing transparency, orderliness, and accessibility.
 
-## 3. Design philosophy of ZenTao Project Management Software
+ZenTao management concept is built on the 3 popular management methodologies: Scrum, Waterfall, and Kanban:
 
-The main design philosophy of ZenTao Project Management Software is based on Scrum, an internationally popular Agile methodology. Scrum is very pragmatic and easy to operate, so it fits in the fast iterative development of software projects. However, Scrum only defines the core management framework. There are still many details and processes that have to be extended and developed. Based on the philosophy of Scrum and with the observation of the current development situations in China, ZenTao integrates bug management, test case management, release management and document management, and it completely covers the entire lifecycle of software development. In ZenTao, the concepts of product, project and test are clearly defined. Product team, development team and QA team coordinate and check with each other while they function differently. The three teams interact with each other through stories, tasks and bugs, and eventually deliver the product with quality.
+- The Scrum model built-in ZenTao is adaptable and flexible, which perfectly matches the rapid iterations of software development projects.
+- The Waterfall model built-in ZenTao lays emphasis on stages division and strict process control, which is ideal for projects that are well defined in advance and with fewer changes.
+- The Kanban model built-in ZenTao pays more attention to value flow and visualization, which is suitable for the team with a transparent process and efficient transmission of information.
 
-## 4. Why choose ZenTao Project Management Software?
+ZenTao clearly defines the concepts of product, project, and QA to help the product owners, developers, and testers coordinate with each other while maintaining separate functionalities. Through stories, tasks, and bugs, the whole teams interact and track issues and improvements to ensure the delivery of quality products.
 
-* ZenTao is a professional development project management software and cannot be replaced by any simple project management software.
-* ZenTao has precise and pragmatic management philosphy, which will accelerate Agile development.
-* ZenTao has full features as a project management software, so you don’t have to integrate several systems together, like mantisbt + trac + testlink.

+
+# 介绍
+
+禅道是第一款国产的开源项目管理软件。它集产品管理、项目管理、质量管理、文档管理、 组织管理和事务管理于一体，是一款专业的研发项目管理软件，完整地覆盖了项目管理的核心流程。
+
+禅道管理思想注重实效，功能完备丰富，操作简洁高效，界面美观大方，搜索功能强大，统计报表丰富多样，软件架构合理，扩展灵活，有完善的 API 可以调用。
+
+# 设计理念
 
 禅和道是中国文化中极具代表意义的两个字，是中国传统文化的结晶。我们之所以选用“禅道”作为我们软件的名字，是希望通过这两个字来传达我们对管理的理解和思考。我们希望通过禅道来进行的管理，可以摒弃繁文缛节，还原管理的本质！
 
-三、禅道的设计理念
+禅道项目管理软件的主要管理思想基于国际流行的`Scrum`模型、瀑布模型和看板模型三种项目管理方法：
 
-禅道项目管理软件的主要管理思想基于国际流行的敏捷项目管理方 式——Scrum。scrum是一种注重实效的敏捷项目管理方式。它规定了核心的管理框架，但具体的细节还需要团队自行扩充。禅道在遵循其管理方式基础上，又融入了国内研发现状的很多需求，比如bug管理，测试用例管理，发布管理，文档管理等。因此禅道不仅仅是一款scrum敏捷项目管理工 具，更是一款完备的项目管理软件。基于scrum，又不局限于scrum。
+- `Scrum`模型方法注重实效，操作性强，非常适合软件研发项目的快速迭代开发。
 
-禅道还首次创造性的将产品、项目、测试这三者的概念明确分开，互相配合，又互相制约，通过需求、任务、bug来进行交相互动，终通过项目拿到合格的产品。 
+- 瀑布模型方法注重阶段清晰、流程严谨、范围可控，非常适合预先有明确定义且变动不大的产品研发管理。
 
-四、选择禅道的八大理由：
-1. 开源的软件，保证了您使用的放心和灵活。
-2. 先进的管理思想，让您在竞争中拔得头筹。
-3. 完备的管理功能，无需再整合其他多个系统。
-4. 国产软件，中文支持，操作习惯更符合国人。
-5. 灵活的扩展机制，可以保证您不局限于禅道自身的功能。
-6. 日趋完善的社区机制，可以获得及时的技术支持和帮助，保证您无后顾之忧。
-7. 几乎为零的投入，禅道作为开源软件，其投入几乎为零，相比动辄十几万的商业软件，您选择禅道没有任何风险。
-8. 开发团队已经公司化运作，保证软件的持久发展。我们从04年从事开源软件开发以来，已经坚持了六年。
+- 看板模型方式注重价值流转和可视化，非常适合流程公开透明和信息高效传递的团队。
 
-五、禅道的功能列表：
+禅道首次创造性的将产品、项目、测试这三者的概念明确分开，产品人员、开发团队、测试人员，三者分立，互相配合，又互相制约，通过需求、任务、`BUG` 来进行交相互动，终通过项目拿到合格的产品。
 
-1. 产品管理：包括产品、需求、计划、发布、路线图等功能。
-2. 项目管理：包括项目、任务、团队、build、燃尽图等功能。
-3. 质量管理：包括bug、测试用例、测试任务、测试结果等功能。
-4. 文档管理：包括产品文档库、项目文档库、自定义文档库等功能。
-5. 事务管理：包括todo管理，我的任务、我的Bug、我的需求、我的项目等个人事务管理功能。
-6. 组织管理：包括部门、用户、分组、权限等功能。
-7. 统计功能：丰富的统计表。
-8. 搜索功能：强大的搜索，帮助您找到相应的数据。
-9. 灵活的扩展机制，几乎可以对禅道的任何地方进行扩展。
-10. 强大的api机制，方便与其他系统集成。
- 
+在数据可视化、度量、`DevOPS`、文档资产管理和自动化测试等模块的加持下，禅道软件形成了项目流程管理、`DevOps`一体化、自动化测试等三大解决方案，完整的覆盖了产品研发的全生命周期管理，助力广大企业高效协作、降本提效。
