How can I synchronise Kanbanchi with my Google calendar?

It’s possible to push Start Date and Due Date of a card, and also the Entire event to your Google calendar. To do it click on a card to open Card Details, then choose Start & Due date property and click “Add to Google Calendar” on the right.

Note, that the integration is one-sided. If you change dates in Kanbanchi, they will change in your Google calendar but the changes you make in your calendar will not be reflected in Kanbanchi cards.
