[Silverteal]

Is your feature request related to a problem? Please describe. 在现有版本中，config.json由主程序生成，但是没有任何修改config.json的清晰指引，只能自己猜

Describe the solution you'd like 在wiki中添加config.json文档

In the current version, config,json is generated by main program, but it don't have the edit instruction for config.json, only can guess by myself.
