 # SignOffice
 
-Office文件签名程序
\ No newline at end of file
+Office文件签名程序
+
+支持docx,xlsx签名
+
+## 签名方式
+~~~
+SignOffice.exe C:/test.xlsx "签名文字=test;签名图片=pic:C:/test.png"
+~~~
+
+## word签名设置
+有两种方式:
+1. 通过设置属性的方式签名文字
+2. 通过设置在单元格内的书签的方式进行签名，这种方式既可以签名图片，也可以签名文字，放在单元格内也会让图片的大小和单元格一致，**推荐使用这种**
+
+## excel签名设置
+通过设置单元格的名称即可
+
+图片会自动适应单元格大小
