+# 10 gobang
+
+## Requirements
+
+1. Run the code in console using command line.
+2. It'll open a Python window to let 2 players play gobang game.
+
+## What will we practice in this project?
+
+- turtle draw
+- mouse click event handle
+- 2d array
+- list
+- exception handle
+- function
+

+## 项目练习
+
+- turtle工具包
+- 自定义函数
+- 二维列表
+- 鼠标事件
