-## Why
+## 目标
 
--   Explore the Go language by writing tests
--   **Get a grounding with TDD**. Go is a good language for learning TDD because it is a simple language to learn and testing is built-in
--   Be confident that you'll be able to start writing robust, well-tested systems in Go
--   [Watch a video, or read about why unit testing and TDD is important](why.md)
+* 掌握Go语言基础
+* 掌握测试驱动方法(TDD)
