+## Configure Rsbuild
+
+In Rslib project, you can configure Rsbuild related configurations in both `lib` configuration object and shared configuration section.
+
+Common-used Rsbuild configurations in library development are listed at [Rsbuild Configuration](/config/rsbuild).
+
+You can also refer to the [Rsbuild Configuration](https://rsbuild.dev/config/index#config-overview) for checking the complete configuration items.
+
+## Configure Rspack
+
+Rslib is built on top of Rsbuild and Rsbuild supports directly modifying the Rspack configuration object and also supports modifying the built-in Rspack configuration of Rsbuild through `rspack-chain`. This means you can configure Rspack related configurations in an Rslib project as well.
+
+For more details, refer to [Configure Rspack](https://rsbuild.dev/guide/basic/configure-rspack).
+
 ## Configuration Debug
 
 You can enable Rslib's debug mode by adding the `DEBUG=rsbuild` environment variable when executing a build. It will display the final Rsbuild/Rspack configuration after processing by Rslib.
