User Guide

Introduction

Duke is an offline application for managing various tasks. It is optimised for those who prefer to work with a Command Line Interface (CLI) while still having the benefits of a Graphical User Interface (GUI).

Features

DES is short for description
Words in UPPER CASE are the parameters to be supplied by the user e.g. in todo TASK DES, TASK DES is the parameter, which can be used as todo borrow book
In the examples, words in the diamond brackets (<>) are user inputs, and Duke responses are have a ‘____’ preceding and succeeding it.
The format for DATE TIME is
```
  dd/mm/yyyy <time in 24hr format>
```
