你的项目文件结构可能和这个类似，但要记得，数据通常都不保存在仓库
中。将项目的数据文件保存在共享文件服务器或本地网络的其他位置。如果
你是独立开发，一定要在其他地方备份。不要将这些大文件提交到你的仓库
中。这样不仅会在需要在新设备上查看仓库时降低工作效率，而且也不是管
理数据的好方法。
我们也建议不要将
db
文件或任何
log
、
config
文件提交到仓库中。仓库结构应尽可能实用。
你总是可以将预期的文件结构添加到
README.md
文件中，并详细说明去哪里获取数据文
件。
Git
和
.gitignore
文件
如果你还没有用
Git
（
https://git-scm.com/
）做版本控制的话，学完本书就会用了！版本
控制可以让你创建仓库来管理和修改代码，并将其分享给团队或其他同事。
在第
14
章中我们将会深入讲解
Git
，但现在我们在讨论仓库结构，希望重点说一
下
.gitignore
文件（
https://github.com/github/gitignore
）。
.gitignore
文件的作用是，让
Git
忽略某些文件，不要将这些文件上传到仓库中。这个文件使用简单模式来匹配文件名，
与我们在第
7
章中学过的正则表达式类似。
在我们的仓库结构中，我们可以用一个
.gitignore
文件，这样
Git
就不会将任何数据文件
提交到仓库中。然后我们可以在
README.md
中说明仓库的结构，给出获取数据文件的
联系信息。这样我们的仓库就比较简洁，且易于下载，还可以保持良好的代码结构。
创建一个符合逻辑的仓库结构，并添加
README.md ...
