Exploring the World of Car Rental Management: Building a Python Application

Part 32: Creating User Manuals for Customers and Staff

Welcome to part 32 of our series on building a car rental management system using Python! In this installment, we'll focus on creating user manuals for both customers and staff. These manuals will serve as comprehensive guides to help users navigate and utilize the application effectively.

Why User Manuals Are Important

User manuals are critical for ensuring that both customers and staff can use the application efficiently. They help to:

• Minimize confusion: Clear instructions prevent common mistakes.

• Reduce support requests: Users can resolve issues independently by referring to the manual.

• Enhance user experience: Well-documented features improve overall satisfaction.

Structuring User Manuals

User manuals should be structured logically, starting from basic operations to more advanced functionalities. Here’s a suggested structure:

1. Introduction

2. Getting Started

3. Main Features

   • For Customers

   • For Staff

4. Troubleshooting

5. FAQs
