文档如何组织

Django有大量文档. 高水平的组织概述可以帮助你如何找到你需要的内容:

• 教程(Tutorials) 如果你初次接触Django或web应用开发, 可以从这里开始, 手把手教你通过一些列的步骤来创建一个web应用程序, . 也可以从 “第一步” 开启学习之旅.
• 主题指南(Topic guides) discuss key topics and concepts at a fairly high level and provide useful background information and explanation.
• 参考指南(Reference guides) contain technical reference for APIs and other aspects of Django’s machinery. They describe how it works and how to use it but assume that you have a basic understanding of key concepts.
• How-to guides are recipes. They guide you through the steps involved in addressing key problems and use-cases. They are more advanced than tutorials and assume some knowledge of how Django works.
