+## Environment and Prerequisite
+
+The script can work directly on QRadar (Tested on 7.5.X) or on a remote Linux machine (Debian) meeting the requirements (preferred method).
+
+### Working Directly on QRadar
+
+**Qradar > 7.5.0 (Python 3.6 (Use of f-strings))**
+
+The script has been designed with flexibility in mind. For those who have direct access and the required privileges, the script can operate directly on a QRadar system. We have verified its compatibility with QRadar versions 7.5.x. This direct method allows for streamlined integration and quick access to QRadar's features without the need for additional configurations.
+
+However, there are some considerations when working directly on QRadar.
+
+### Working on a Remote Linux Machine (Preferred Method)
+
+For a more isolated and controlled environment, we recommend executing the script on a remote 🐧 Linux machine. Our tests have particularly been positive on Debian-based systems.
+
+This method has several advantages:
+
+- 🏝️ **Isolation:** Running the script remotely ensures that QRadar's primary functions remain undisturbed. There's no risk of unintentionally consuming excessive resources on the QRadar system.
+- 🤸 **Flexibility:** A separate Linux machine provides more freedom for customization, debugging, and script optimization. This can be especially beneficial when integrating the script with other tools or systems.
+- 🛡️ **Security:** Operating the script remotely can add a layer of security. By limiting direct access to the QRadar system, you can further safeguard against potential threats or mishaps.
+
+#### 📋 Requirements for the Remote Linux Machine:
+
+- **Python Version:** Ensure that Python is installed, preferably a version that supports f-strings (Python 3.6 and above).
+- **Network Access:** The remote machine should have network access to QRadar for API calls. Ensure that any firewalls or security groups allow for the necessary communication between the two systems.
+- **Required Libraries:** The script might rely on specific Python libraries. These should be installed and kept updated on the remote machine.
+- **Authentication:** API authentication details, like tokens or credentials, should be securely managed. Consider using environment variables or secure configuration files.
+
+##### 🧪 Tested on my side on:
+
+- debian Bullseye (11.7)
+- Python 3.9.2
+- Requests==2.31.0
+- urllib3==1.26.5
