 A few Transformers are built into this plugin, including:
 
-- `createTransformerDiff`: Implementation of the diff highlighting effect of the code block.
 - `createTransformerLineNumber`: Implement the display of the line number of the code block.
-- `createTransformerErrorLevel`: Implement the display of the error level of the corresponding line of the code block, including `error` and `warning`.
-- `createTransformerHighlight`: Implement line highlighting display of the code block.
-- `createTransformerFocus`: Implement line focus display of the code block.
 
 You can enable these Transformers by configuring the `transformers` attribute, such as:
 
 ```ts title="rspress.config.ts"
 import { defineConfig } from 'rspress/config';
 import { pluginShiki, createTransformerDiff } from '@rspress/plugin-shiki';
+import {
+  transformerNotationDiff,
+  transformerNotationErrorLevel,
+  transformerNotationFocus,
+  transformerNotationHighlight,
+} from '@shikijs/transformers';
 
 export default defineConfig({
   plugins: [
     pluginShiki({
       transformers: [
         // Add as needed
-        createTransformerDiff(),
-        // createTransformerLineNumber(),
-        // createTransformerErrorLevel(),
-        // createTransformerHighlight(),
-        // createTransformerFocus(),
+        createTransformerLineNumber(),
+        // transformerNotationDiff(),
+        // transformerNotationErrorLevel(),
+        // transformerNotationHighlight(),
+        // transformerNotationFocus(),
       ],
     }),
   ],
 });
 ```
 
-Then let us introduce how to use the syntax corresponding to these Transformers.
-
-#### Diff highlighting
-
-Use the `diff` syntax in the markdown code block, such as:
-
-```ts
-export function foo() {
-  console.log('Diff remove'); // [!code --]
-  console.log('Diff add'); // [!code ++]
-}
-```
-
-This will automatically apply the diff highlighting effect to the corresponding line of code.
-
-#### Line number display
-
-Use the `hl` syntax in the markdown code block, such as:
-
-```ts
-export function foo() {
-  console.log('Line number'); // [!code hl]
-}
-```
-
-This will automatically display the line number for the corresponding line of code.
-
-#### Error level display
-
-Use the `error` or `warning` syntax in the markdown code block, such as:
-
-```ts
-export function foo() {
-  console.log('Error level'); // [!code error]
-}
-```
-
-This will automatically display the error level for the corresponding line of code.
-
-#### Line focus display
-
-Use the `focus` syntax in the markdown code block, such as:
-
-```ts
-export function foo() {
-  console.log('Focus'); // [!code focus]
-}
-```
-
-This will automatically display the focus effect for the corresponding line of code.

 本插件中内置了一些 Transformer，包括：
 
-- `createTransformerDiff`：实现代码块的 diff 高亮效果。
 - `createTransformerLineNumber`：实现代码块的行号显示。
-- `createTransformerErrorLevel`：实现代码块对应行的错误等级显示，包括 `error` 和 `warning`。
-- `createTransformerHighlight`：实现代码块的行高亮显示。
-- `createTransformerFocus`： 实现代码块的行聚焦显示。
 
 你可以通过配置 `transformers` 属性来启用这些 Transformer，比如：
 
 ```ts title="rspress.config.ts"
 import { defineConfig } from 'rspress/config';
 import { pluginShiki, createTransformerDiff } from '@rspress/plugin-shiki';
+import {
+  transformerNotationDiff,
+  transformerNotationErrorLevel,
+  transformerNotationFocus,
+  transformerNotationHighlight,
+} from '@shikijs/transformers';
 
 export default defineConfig({
   plugins: [
     pluginShiki({
       transformers: [
         // 按需加入即可
-        createTransformerDiff(),
-        // createTransformerLineNumber(),
-        // createTransformerErrorLevel(),
-        // createTransformerHighlight(),
-        // createTransformerFocus(),
+        createTransformerLineNumber(),
+        // transformerNotationDiff(),
+        // transformerNotationErrorLevel(),
+        // transformerNotationHighlight(),
+        // transformerNotationFocus(),
       ],
     }),
   ],
 });
 ```
 
-接着我们来介绍一下如何使用这些 Transformer 对应的语法。
-
-#### diff 高亮
-
-在 markdown 的代码块中使用 `diff` 语法，比如：
-
-```ts
-export function foo() {
-  console.log('Diff remove'); // [!code --]
-  console.log('Diff add'); // [!code ++]
-}
-```
-
-这样会自动对相应行的代码应用 diff 高亮效果。
-
-#### 行号显示
-
-在 markdown 的代码块中使用 `hl` 语法，比如：
-
-```ts
-export function foo() {
-  console.log('Line number'); // [!code hl]
-}
-```
-
-这样会自动对相应行的代码显示行号。
-
-#### 错误等级显示
-
-在 markdown 的代码块中使用 `error` 或 `warning` 语法，比如：
-
-```ts
-export function foo() {
-  console.log('Error level'); // [!code error]
-}
-```
-
-这样会自动对相应行的代码显示错误等级。
-
-#### 行聚焦显示
-
-在 markdown 的代码块中使用 `focus` 语法，比如：
-
-```ts
-export function foo() {
-  console.log('Focus'); // [!code focus]
-}
-```
-
-这样会自动对相应行的代码显示聚焦效果。
