 |data_dir|数据目录, 存储中间文件或者模型文件的|
 |naming|命名规则, 可用的命名标签如下:{DATE}, {YEAR}, {MONTH}, {NUMBER}, {ACTOR}|
 
+工具并不会对番号进行清洗(各种奇奇怪怪的下载站都有自己的命名方式, 无脑清洗可能会导致得到预期外的番号), 用户自己需要对文件进行重命名。
+
+当前支持给番号添加特定来后缀来实现`添加额外分类`, `添加特定水印`等能力。
+
+支持的后缀列表及说明(不同的后缀没有顺序限制, 可以同时存在多种后缀):
+
+|后缀|举例|说明|
+|---|---|---|
+|-CD{Number}|-CD1|多CD场景下, 指定当前影片对应的CD ID, 起始CD为1|
+|-C|-|添加`字幕`到分类中并为封面添加水印|
+|-4K|-|添加`4K`到分类中并为封面添加水印|
+|-LEAK|-|为封面添加特定水印|
