How to add library to arduino other than PlatformIO

[ChanSeongKim]

Hi~
Thank you for your library. I managed to succeed making your library run in PlatformIO environment. Then I'd like to know how to add library in Arduino IDE.

Can u advise me how to add library in arduino ide?
I googled how to add library to arduino ide then I tried but failed.

Thank you in advance.
