 # BaseProject
 #项目介绍：
   本项目(Android库工程)为Android开发APP的通用模版框架，皆在使用本框架能快速开发Android项目尤其是含有网络请求的项目，优化项目代码结构、模块化编程。
-本项目力求能给阅读者、使用者在Android项目架构能力方面带来一定的速度、质量的提升。
+本项目力求能给阅读者、使用者在Android项目架构能力方面带来一定的速度、质量的提升，该版本为base分支。
 
 #给取个名吧：
   BaseProject --> 基础工程 --> 能帮助Android开发者大众 --> 倒是想像济公，普渡众人(有点大了啊！！)--> 济公他老人家肯定不乐意，也怕其实难副!-->那就偕个音，就叫“基工”吧，
