This is an old revision of the document!
At the core of a Kanban system (including this one) is a concept called a card. A card contains a title and some contents. Optionally you can add any number of comments on the card, and set its option too. You can also send the card into a Google Calendar.
The date and time for both the creation and update of the card would be visible when you hover the mouse over the time statement on the card.
NOTE: A small amount of credits are needed to create a card. Refer our pricing page.
