 arduino-cli-install
-===================
+===================
+
+The ``arduino-cli-install`` script is a cross-platform Python utility that automates the installation of the `Arduino CLI <https://arduino.github.io/arduino-cli/>`_ tool on Linux, macOS, and Windows systems.
+
+Arduino CLI is a command-line interface that provides all the functionality of the Arduino IDE in a scriptable and automatable way. It's particularly useful for continuous integration (CI) workflows, automated testing, and batch operations.
+
+Features
+--------
+
+- **Cross-platform support**: Works on Linux, macOS, and Windows
+- **Version-specific installation**: Install any specific version of Arduino CLI
+- **Automated download and setup**: Handles downloading, extracting, and placing the executable in the system PATH
+- **Error handling**: Provides clear error messages if installation fails
+
+Usage
+-----
+
+Basic usage:
+
+.. code:: bash
+
+    python arduino-cli-install.py <version>
+
+Where ``<version>`` is the specific version of Arduino CLI you want to install.
+
+Examples
+^^^^^^^^
+
+Install a specific version:
+
+.. code:: bash
+
+    python arduino-cli-install.py 0.34.2
+
+Installation process
+--------------------
+
+The script performs the following steps based on your operating system:
+
+**Linux and macOS:**
+
+1. Downloads the appropriate tar.gz archive from the Arduino CLI releases
+2. Extracts the archive
+3. Moves the executable to ``/usr/local/bin/`` (requires sudo privileges)
+4. Cleans up temporary files
+
+**Windows:**
+
+1. Downloads the Windows zip archive using PowerShell
+2. Extracts the archive
+3. Moves the executable to ``C:\Windows\System32\`` (requires administrator privileges)
+4. Cleans up temporary files
+
+Prerequisites
+-------------
+
+- Python 3.x installed on your system
+- Internet connection to download Arduino CLI
+- Administrator/sudo privileges for system-wide installation
+- On Linux/macOS: ``curl`` and ``tar`` commands available
+- On Windows: PowerShell available
+
+.. note::
+    The script installs Arduino CLI system-wide, making it available from any directory in your terminal or command prompt.
+
+.. warning::
+    This script requires elevated privileges (sudo on Linux/macOS, administrator on Windows) to install Arduino CLI in system directories. Make sure you trust the source before running with elevated privileges.
