Miku User Guide

Miku is a task-focused chatbot that helps you track todos, deadlines, and events in a fast, command-driven workflow.

Quick start

1. Install Java 17 or later.
2. Download Miku.jar.

3. In the same folder as the jar, run:

    java -jar Miku.jar
   

4. Type commands in the input box and press Enter.

Command format notes

• Commands are case-insensitive (e.g., LiSt works the same as list).
• Indexes are 1-based and refer to the list shown in the UI.
• For mark, unmark, and delete, you can use a single index, a comma list, or a range.
• Date/time input uses the format yyyy-MM-dd HH:mm.
