 ### 你需要知道的几个事情
 
 - 因为没有打包, 所以所有的文件引用都是按源代码的结构, 对于源码的保护比较弱(虽然打包也没约等于没保护, 因为前端没秘密)。
-- 因为是用的是原生的`ESM`,所以引用的**依赖/文件**, 需要完整的路径, 可以省略后缀名, 但不能省略`index.js/index.vue`。
+- 因为是用的是原生的`ESM`,所以引用的**依赖/文件**, 需要完整的路径, 可以省略后缀名(不推荐), 但不能省略`index.js/index.vue`。
 - 因为没有内置完整的样式处理,支持`scoped`、`:deep()`, 但不支持`:global()`。
-- `单文件组件`中的样式, 如果是用scss, 不支持引用其他文件, 也不支持设置共用定义文件。
+- `单文件组件`中的样式, 如果是用scss, 不支持引用其他文件。
 - 样式预处理器, 只支持scss, 不支持less。
