 The configs of [html-rspack-plugin](https://github.com/rspack-contrib/html-rspack-plugin) can be modified through `tools.htmlPlugin`.
 
-:::tip
 Rsbuild internally implements HTML-related features based on [html-rspack-plugin](https://github.com/rspack-contrib/html-rspack-plugin). It is a fork of [html-webpack-plugin](https://github.com/jantimon/html-webpack-plugin), with the same features and options.

+:::tip
+If you need to modify options such as `title`, `template`, `templateParameters`, `meta`, it is recommended to use the corresponding HTML configurations provided by Rsbuild first, such as [html.title](/config/html/title), [html .template](/config/html/template) etc.
+
+This is because Rsbuild provides some internal optimization processing for these HTML configurations. For example, if the HTML template used by the current project already contains the `<title>` tag, then `html.title` will not take effect.

 Rsbuild 内部基于 [html-rspack-plugin](https://github.com/rspack-contrib/html-rspack-plugin) 实现 HTML 相关的能力。它是 [html-webpack-plugin](https://github.com/jantimon/html-webpack-plugin) 的一个 fork 版本，具备完全一致的功能和选项。
+
+:::tip
+如果你需要修改 `title`、`template`、`templateParameters`、`meta` 等选项，推荐优先使用 Rsbuild 提供的对应 HTML 配置项，如 [html.title](/config/html/title)、[html.template](/config/html/template) 等。
+
+这是因为这些配置间存在一些关联关系，Rsbuild 对于 HTML 配置项提供了一些内部的优化处理，例如，如果当前项目使用的 HTML 模板中已经包含了 `<title>` 标签，那么 `html.title` 将不会生效。
