+# Netclient assets
+
+Run `scripts/download-netclient-assets.bat` on Windows or `pwsh scripts/download-netclient-assets.ps1` before building the desktop app.
+
+Expected files:
+
+- `windows/netclientbundle.exe`
+- `windows/netclient-windows-amd64.exe`
+- `macos/Netclient-M1.pkg`
+- `macos/Netclient-Intel.pkg`
+- `macos/netclient-darwin-arm64`
+- `macos/netclient-darwin-amd64`
+
+The app first looks for an installed `netclient`, then falls back to the bundled binary. If `netclient` is missing, the install button starts the bundled installer with administrator privileges.
