+Plugin name: `valaxy-addon-<name>`.
 
+> Add-on, compared to Plug-in, typically implies modifications to the user interface, as well as being applicable only on a specific platform.
+> For example, the Edge Add-on Store, Slidev, and others use the naming convention "Addon".

+> Valaxy fully supports the use of Vite and Vue ecosystem plugins.
+> In addition, we may also require support for some plugins that are specific to Valaxy, which can control the entire process before the Vite/Vue plugins are executed.
+>
+> In this scenario, the Addon API is only applicable to the Valaxy platform.

 插件可以做什么？
 
 譬如制作一个 Live2D 挂件，一个全局音乐播放器，或是修改 Vite 以及内置插件的一些配置等。
 
 它用于补充 Vite/Vue 插件无法做到或加载配置繁琐的内容。

+::: en
+What can addons do?
+
+For example, they can create a Live2D widget, a global music player, or modify some configurations of Vite and its built-in plugins.
+
+Addons are used to complement what Vite/Vue plugins cannot achieve or to simplify complicated configurations.
