+## 说明
+使用该程序来对MyDumper导出的CSV数据进行读取，转换，然后导出到其他数据库中。
+
+1. 用MyDumper从数据库导出CSV数据  
+
+   使用MyDumper Docker镜像
+    ```sh
+    docker run --rm --net=host -v D:/Dump:/home/backup mydumper/mydumper:v0.15.2-6 mydumper `
+   -h 127.0.0.1 -P 33306 -u root -p 123456 `
+   -B cferp_test --no-schemas --csv --hex-blob `
+   -o /home/backup
+    ```
+   将挂载卷，数据库连接和输出目录替换  
+   不导出数据库结构(--no-schemas)，
+   导出完的目录下应当包含.sql文件以及.dat文件
+
+2. 在Program.cs中修改`CsvOptions`配置
+   ```cs
+   host.Services.Configure<CsvOptions>(option =>
+    {
+        option.Delimiter = ",";
+        option.QuoteChar = '"';
+        option.InputDir = "D:/Dump/Test";
+    });
+   ```
+   将`option.InputDir`配置为MyDumper导出的数据目录
+
+3. 在Program.cs中修改`DatabaseOutputOptions`配置
+   ```cs
+   host.Services.Configure<DatabaseOutputOptions>(options =>
+    {
+        options.ConnectionString = new MySqlConnectionStringBuilder
+        {
+            Server = "127.0.0.1",
+            Port = 33306,
+            Database = "cferp_test_1",
+            UserID = "root",
+            Password = "123456",
+            MaximumPoolSize = 50, 
+        }.ConnectionString;
+        options.MaxTask = 16;
+        options.FlushCount = 200;
+    });
+   ```
+   将`MySqlConnectionStringBuilder`的属性修改为程序要导出至的数据库
+   > 后续将这些配置通过命令行传递
+
+4. 运行程序
+   > 注意，测试数据库`cferp_test`中的`order_process_step`表存在外键，如果要导出到和测试库同结构的数据库，记得先把外键删除。
