+### Desktop Launcher
+
+After installation, a launcher script `lazy-update-manager-electron` is placed in `~/.local/bin/`. It sets the project directory and starts Electron directly. This is also what the desktop entry (wofi/rofi) uses.
+
+When running `lazy-update-manager gui` from the terminal, the Go backend tries to start the Electron app automatically when `prefer_electron` is enabled (default after installation). You can force the web interface with `lazy-update-manager gui web`.

 ## Install

+- a desktop entry to `~/.local/share/applications/lazy-update-manager.desktop`
 - the user service and timer to `~/.config/systemd/user/`
 
-When a user systemd session is available, the timer is enabled immediately so update notifications work after install.
+The installer also runs `npm install`, builds the Go backend, sets `prefer_electron: true` in the config, and enables the systemd timer.
 
-The install target now preserves the previous binary by backing it up when it differs, so installations are safe and reversible.
