+
+# Introduction 
+
+The purpose of the application is to manage a library using Java Object-Oriented Programming.
+
+The application includes 5 classes:
+* Book
+* Librarian
+* Library
+* Main
+* User
+
+You can sign up or login if you already have an account as a ordinary user who can borrow a book, or as a librarian who manages the library.
+
+
+# Structure
+
+* The `Library` class is the most important , and also, class `Main` runs the program by calling the method called `runMenu()`.
+* The methods `newUserSignUp()` and `newLibrarianSignUp()` are created in `Main` to let new users sign up as either an ordinary user or a librarian.
+* Users can borrow and return books from the library by `rentBook()` and `returnBook()` methods, respectively, defined in `User` class.
+* The add, update, search, remove operations on all books and users objects are accessed only by librarians. These methods are defined in `Library` class.
+* A Librarian can also borrow or return books due to it’s inheritance of `User` class.
+* Librarian can, also, add or remove another librarian. 
+
+# Bonus
+In my implementation:
+
+* Usernames are unique
+* A book cannot be borrowed twice
+* The user cannot return the book that has not been borrowed
+* All fields are private, and proper getters and setters are defined
+* All functionalities are available from GUI
+
+# Conclusion:
+* By this project, I've used basic concepts of object-oriented programming in an example.
+* I, also, experienced working with access modifiers, public and private methods.
+* I broke my code into individual classes that helped me increasing the readability of my code
+* I didn't provide a back and exit command
