 ## Install into DSH
 
-Build the DSH package, then install its local profile bundle into the Web profile:
+Build the DSH package first:
 
 ```powershell
 pnpm --filter ./dsh-plugin build
+```
+
+For a normal CLI profile, install the local bundle into the default Web profile:
+
+```powershell
 dsh plugin --profile web add -w F:\dsh-plugin-coop-with-vs\dsh-plugin
 ```
 
-The package's `cordis.patch.yml` inserts its own shared Host/Client row. Restart `dsh web` after the first install. During development, run the DSH package watcher and the Harness `pnpm run dev:web` watcher when Client HMR is required.
+The packaged DeepSeek Harness desktop app uses an isolated `DSH_HOME` below its Electron user-data directory. Set that path for the install command so the desktop sidecar, rather than only the default CLI profile, receives the bundle:
+
+```powershell
+$env:DSH_HOME = "$env:APPDATA\deepseek-harness-desktop\dsh"
+$DshCli = 'F:\deepseek-harness-desktop\.artifacts\windows-electron\win-unpacked\resources\runtime\app\node_modules\@deepseek-ai\dsh\lib\bin.js'
+node $DshCli plugin --profile web add -w 'F:\dsh-plugin-coop-with-vs\dsh-plugin'
+```
+
+The package's `cordis.patch.yml` inserts its own shared Host/Client row. Fully quit and restart the matching DSH process after the first install. During development, run the DSH package watcher and the Harness `pnpm run dev:web` watcher when Client HMR is required.
 
 Install the generated VS Code `.vsix` and Visual Studio `.vsix` from their component output directories. Once either IDE companion is active, type `@` in the DSH composer and select from the `IDE open files` group.
