 The previous tutorials loaded a local plugin through a `--patch` overlay. This tutorial packages it as an installable **bundle**, installs it into a **profile** with `dsh plugin add`, and explains the layer order that determines the composed configuration. It assumes the `dsh` CLI is installed. Complete [plugin configuration](./config.md) first.
 
+To use a fresh source checkout instead, complete the [run-from-source section](../../../../README.md#run-from-source), keep this tutorial's `hello-plugin` directory at the repository root, and run the remaining `dsh ...` commands from there as `pnpm dsh ...`. See [source execution](../../../../apps/cli/reference/README.md#source-execution) for build and launcher behavior.

 ## Two concepts, two manifests
 
 Installation is built on two concepts. Both are described by a `package.json`, but they carry different kinds of manifest under the `dsh` key, and they answer different questions:

 前几篇教程通过 `--patch` overlay 加载本地插件。本教程把它打包成可安装的**组合包**（bundle），用 `dsh plugin add` 安装进一个 **profile**，并解释决定组合后配置的层顺序。本文假设 `dsh` CLI 已安装。请先完成[插件配置](./config.md)。
 
+如果改用全新的源码 checkout，请先按照[从源码运行章节](../../../../README.md#run-from-source)完成准备，将本教程的 `hello-plugin` 目录放在仓库根目录，并从该目录把下文的 `dsh ...` 命令改为 `pnpm dsh ...`。构建与启动器行为见[源码执行](../../../../apps/cli/reference/README.md#source-execution)。

 ## 两个概念，两种 manifest
 
 安装机制建立在两个概念之上。二者都由一份 `package.json` 描述，但它们在 `dsh` 键下携带的 manifest（元数据清单）种类不同，回答的问题也不同：
