 主题在代码高亮功能上，进一步支持了更多的特性，它们能够帮助你的代码块更加具备表达力。
 
+## 代码行号
+
+主题默认显示代码行号，它通过 `plugins.shiki.line-numbers` 来控制。
+
+```ts
+export default defineUserConfig({
+  theme: plumeTheme({
+    plugins: {
+      shiki: { lineNumbers: true }
+    }
+  })
+})
+```
+
+你还可以通过 `:line-numbers` / `:no-line-numbers` 来控制当前代码块是否显示代码行号。
+
+**输入：**
+
+````
+```ts:line-numbers
+// 启用行号
+const line2 = 'This is line 2'
+const line3 = 'This is line 3'
+```
+
+```ts:no-line-numbers
+// 行号已禁用
+const line3 = 'This is line 3'
+const line4 = 'This is line 4'
+```
+````
+
+**输出：**
+
+```ts:line-numbers
+// 启用行号
+const line2 = 'This is line 2'
+const line3 = 'This is line 3'
+```
+
+```ts:no-line-numbers
+// 行号已禁用
+const line3 = 'This is line 3'
+const line4 = 'This is line 4'
+```
+
 ## 在代码块中实现行高亮
 
 在 `[lang]` 之后紧跟随 `{xxxx}` ，可以实现行高亮，其中 `xxx` 表示要高亮的行号。
