-## Icons naming convention
-
-We provide semantic name for every icon, and naming rules are as follows:
-
-- Scanning line icon has the similar name with its solid one，but it's distinguished by `-o`, for example, `question-circle` (a full circle) and `question-circle-o` (an empty circle);
-- Naming sequence：`[name]-[shape?]-[outline?]-[direction?]`.
-
-> `?` means is optional.
-
-See more design detail at [here](/docs/spec/icon).

-## 图标的命名规范
-
-我们为每个图标赋予了语义化的命名，命名规则如下:
-
-- 实心和描线图标保持同名，用 `-o` 来区分，比如 `question-circle`（实心） 和 `question-circle-o`（描线）；
-- 命名顺序：`[图标名]-[形状?]-[描线?]-[方向?]`。
-
-> `?` 为可选。
