+🧩 How it works
+===============
+
+The ``install_jtop_torun_without_sudo.sh`` script automates a safe,
+user-friendly installation of **jtop** that allows you to run it without
+``sudo``. It performs the following steps:
+
+1. **Safety check**
+
+   - Refuses to run if invoked as ``root`` or via ``sudo``.
+   - Instructs you to run ``sudo -v`` first so that later privileged
+     commands (``apt``, ``systemctl``) can execute without repeated password prompts.
+
+2. **Prepare environment**
+
+   - Verifies whether ``pip3`` and ``pipx`` are installed; if either is missing, installs them via ``apt``.
+   - Ensures ``~/.local/bin`` is on your ``PATH`` so that ``pipx`` applications are available in future shells.
+
+3. **Install jtop via pipx**
+
+   - Uses ``pipx install "git+https://github.com/rbonghi/jetson_stats.git"`` to install the latest version in an isolated user environment.
+   - Determines the correct executable path (usually ``~/.local/bin/jtop`` or inside the pipx venv).
+
+4. **Systemd service setup**
+
+   - Creates or updates ``/etc/systemd/system/jtop.service`` to point to your user’s jtop binary.
+   - Sets safe defaults (``Restart=on-failure``, ``RestartSec=10s``, etc.) to make the service robust.
+
+5. **Enable and start the service**
+
+   - Reloads systemd, enables ``jtop.service`` to start automatically at boot,
+     and restarts it immediately.
+
+6. **Result**
+
+   After installation, you can simply launch jtop from your terminal
+   as a normal user (no ``sudo`` required):
+
+   .. code-block:: bash
+
+      jtop
+
+
+Why use this method
+===================
+
+.. code-block:: text
+
+   • Keeps the system (root) Python environment clean and untouched
+   • Uses pipx’s isolation, making upgrades and uninstalls clean and safe
+   • Fully compatible with Ubuntu 24.04+ and later Debian-based systems
+   • Ensures jtop runs under your user account (avoids root-owned processes)
+   • Provides systemd integration for automatic startup and recovery
