-### 3.2 Installation Procedure
-```bash
-# Clone the repository
-git clone https://github.com/prathameshnium/PICA-Python-Instrument-Control-and-Automation.git
-cd PICA-Python-Instrument-Control-and-Automation
 
-# Create virtual environment (Recommended)
-python -m venv venv
-# Activate: venv\Scripts\activate (Windows) or source venv/bin/activate (Linux/Mac)
+### 3.2 Getting Started
 
-# Install Python dependencies
-pip install -r requirements.txt
+PICA is structured as a standard Python package.
 
-# The base installation does not include gpib-ctypes, which is only required for 
-# specific GPIB hardware on Linux systems (e.g., linux-gpib). 
-# If you need this functionality, install it separately:
-pip install .[gpib]

+    For headless operation (e.g., Raspberry Pi).
+    ```bash
+    pica-cli
+    ```
 > [!WARNING]
 > **CLI Deprecation Notice:** The PICA CLI is comprised of old, deprecated scripts from the early stages of development. It is **strongly recommended to use the PICA GUI** for all interactions. The CLI scripts are considered legacy code, contain minimal functionality for performing set protocols, and are not recommended for general use.

 > [!WARNING]
 > **Safety Instructions:** Always switch off the instrument and verify that the output current, voltage, and any other relevant parameters are set to zero before modifying the connections to the Device Under Test (DUT). Failure to follow appropriate safety procedures may result in electric shock or other hazards. Adopt a safety-first approach at all times, and ensure that all instrument parameters remain within the specified safe operating limits defined either by the instrument manufacturer or by your measurement setup.
