+Usage
+=====
+
+使用方法如下 ::
+
+   from pyatool import PYAToolkit
+
+   device = PYAToolkit('123456F')
+
+   # 直接调用
+   package_list = device.show_package()
+   # 通过标准库（有自动补全）
+   package_list = device.std.show_package(toolkit=device)
+
+   print(package_list)
+
+要调用其他的API，将 `show_package` 替换成API名称即可！
