+# Library Management System (CLI)
+
+A small command-line Library Management System built with Python 3.10+.
+
+This project demonstrates the core concepts covered in Sections 1–6 of the Python Bootcamp, including:
+
+* Comments
+* `print()` and `input()`
+* Conditional statements (`if`, `elif`, `else`)
+* Lists and loops
+* Functions and `main()`
+* File handling (UTF-8)
+* Error handling with `try` / `except`
+* Object-Oriented Programming (OOP)
+* `@dataclass`
+* `__str__()` methods
+* Composition
+
+---
+
+## Run the Project
+
+```bash
+cd 07_final_project_library_management_system
+python main.py
+```
+
+---
+
+## Project Structure
+
+```text
+07_final_project_library_management_system/
+│
+├── main.py
+│
+├── models/
+│   └── books.py
+│
+├── utils/
+│   └── storage.py
+│
+├── data/
+│   └── books.txt
+│
+└── README.md
+```
+
+---
+
+## Features
+
+The system allows a librarian to:
+
+1. Add a new book
+2. View all books
+3. Remove a book
+4. Search for a book by ID
+5. Update book information
+6. Save library data
+7. Quit the application (automatically saves data)
+
+---
+
+## Book Information
+
+Each book contains:
+
+* Book ID
+* Title
+* Author
+* Year Published
+
+Example:
+
+```text
+ID: 101
+Title: Python Basics
+Author: Abdullahi hassan
+Year: 2026
+```
+
+---
+
+## Data Storage
+
+All library data is stored in:
+
+```text
+data/books.txt
+```
+
+The file uses UTF-8 encoding and a simple pipe-separated format.
+
+Example:
+
+```text
+# Library Database
+id|title|author|year
+101|Python Basics|Abdullahi|2026
+```
+
+### Notes
+
+* Lines beginning with `#` are treated as comments.
+* The header row is ignored when loading data.
+* Data is automatically loaded when the application starts.
+* Data is automatically saved when the application exits.
+
+---
+
+## Error Handling
+
+The project uses `try` / `except` blocks to prevent crashes caused by invalid user input.
+
+Examples:
+
+* Entering text instead of a numeric ID
+* Entering an invalid publication year
+* Loading a missing data file
+
+---
+
+## OOP Concepts Used
+
+### Book Class
+
+Represents a single book in the library.
+
+Responsibilities:
+
+* Store book information
+* Display formatted book details using `__str__()`
+
+### Library Class
+
+Represents the entire library collection.
+
+Responsibilities:
+
+* Store books in memory
+* Add books
+* Remove books
+* Search books
+* Manage library records
+
+This demonstrates **composition**, where a `Library` object contains multiple `Book` objects.
+
+---
+
+## Technologies
+
+* Python 3.10+
+* Dataclasses
+* File Handling
+* UTF-8 Text Storage
+* Command-Line Interface (CLI)
+
+---
+
+## Learning Objectives
+
+After completing this project, students should be able to:
+
+* Build a complete CLI application
+* Organize code into modules
+* Work with classes and objects
+* Read and write files
+* Handle user input safely
+* Apply Python best practices
+* Create maintainable project structures
