Under the setCalendars() documentation section https://github.com/nhn/tui.calendar/blob/main/docs/en/apis/calendar.md#setcalendars the interface documentation is shown as

interface CalendarInfo { id: string; name: string; color?: string; bgColor?: string; dragBgColor?: string; borderColor?: string; }

when it should be

interface CalendarInfo { id: string; name: string; color?: string; backgroundColor?: string; dragBackgroundColor?: string; borderColor?: string; }

Other references in the documentation appear to be correct.
