+
+## 如何安装
+
+克隆本项目：
+```bash
+git clone https://github.com/nigo81/import-csv-to-mysql.git
+```
+
+给`csv2mysql`文件添加可执行权限：
+
+```bash
+chmod +x csv2mysql
+```
+
+将`csv2mysql`复制到`~/.local/bin`:
+
+```bash
+cp csv2mysql ~/.local/bin
+```
+
+你需要安装`fzf`搜索工具，因为脚本里调用它来选择文件。
+
+## 如何使用
+
+进入你csv文件所在目录，然后执行`csv2mysql`
+
+
+![fzf](pictures/fzf.png)
+
+你可以使用`fzf`的搜索功能，按下`tab`键可以选中文件。
+
+选择完成后，按下回车确认。

+```
+你需要填写mysql数据库的一些信息，如ip,数据库名称，账号，密码。
+
+你需要在`table name`处输入你将导入的数据保存的表的名称，如果数据库中没有该表，会自动创建。
