+
+可通过`ConfigHelper.Instance.SetLang(string lang)`指定需要使用的语言包，默认使用zh-cn。
+
+控件库自带的语言包一般为控件库内部使用，但用户也可以通过以下两种方式使用：
+
+- xaml
+第一步，引入命名空间：`xmlns:hc="https://handyorg.github.io/handycontrol"`
+第二步，使用语言包：`<TextBlock Text="{x:Static hc:Lang.Cancel}"/>`
+
+- C#
+`HandyControl.Properties.Langs.Lang.Cancel`
+
+{% note warning %}
+控件库不支持动态语言包切换，未来也不会有支持。
+{% endnote %}
+
+# 扩展
+
+控件库自带zh-cn和en两份语言包，默认为zh-cn：
+
+![Langs](images/Langs.png)
+
+如果需要可自行扩展，这里推荐使用开源插件：[ResXManager](https://marketplace.visualstudio.com/items?itemName=TomEnglert.ResXManager)，来维护所有的语言包。
+
+引用控件库后，会在运行目录生成语言包文件夹，其命名方式形如zh-cn、en等。
