Lexi Task Manager - User Guide

Lexi is a desktop app for managing different tasks, including todos, events and deadlines. Lexi is taking advantage of the Command Line Interface and is optimized for that to bring your task management and productivity to a next level.

Features

Notes about the command format:

• Words in UPPER_CASE are the parameters supplied by the user. E.g., in todo DESCRIPTION, DESCRIPTION is a parameter to be replaced with actual data, like todo read book.
• Items in square brackets are optional. E.g., find [KEYWORD] can be used as find or as find book
• Parameters must be provided in the correct order. E.g., if the command specifies deadline DESCRIPTION DUE_DATE, deadline DUE_DATE DESCRIPTION is not acceptable.
