 If you want to prevent some files from triggering a rebuild when they change, you can use Rspack's [watchOptions.ignored](https://rspack.dev/config/watch#watchoptionsignored) configuration item.
 
-For example, to prevent changes in the `node_modules` directory from triggering a rebuild, you can add the following configuration:
-
-```js
-export default {

+## File Watching
+
+By default, Rsbuild does not watching files in the `.git/` and `node_modules/` directories. When files in these directories changed, Rsbuild will not trigger a rebuild. This helps to reduce memory usage and improve build performance.
+
+If you want to watch these directories, you can manually configure Rspack's [watchOptions.ignored](https://rspack.dev/config/watch#watchoptionsignored) to override the default behavior.
+
+For example, to watch the `node_modules/` directory and ignore the `.git/` directory, you can configure it as follows:
+
+```js title="rsbuild.config.ts"
+export default {
+  tools: {
+    rspack: {
+      watchOptions: {
+        ignored: /\.git/,
+      },
+    },
+  },
+};

 如果你希望当某些文件变化时，不触发重新构建，可以使用 Rspack 的 [watchOptions.ignored](https://rspack.dev/config/watch#watchoptionsignored) 配置项。
 
-例如，指定当 `node_modules` 中文件发生变化时，不触发重新构建，可以添加如下配置：

-```js

+## 文件监听
+
+Rsbuild 默认不监听 `.git/` 和 `node_modules/` 目录下的文件，当这些目录下的文件发生变化时，Rsbuild 不会触发重新构建。这有助于减少内存占用和提升构建性能。
+
+如果你希望监听这些目录，可以手动配置 Rspack 的 [watchOptions.ignored](https://rspack.dev/config/watch#watchoptionsignored) 来覆盖默认行为。
+
+例如，监听 `node_modules/` 目录且忽略 `.git/` 目录，可以配置为：
+
+```js title="rsbuild.config.ts"
+export default {
+  tools: {
+    rspack: {
+      watchOptions: {
+        ignored: /\.git/,
+      },
+    },
+  },
+};
