Connect / Disconnect Cards
Each card has a in joint (on the top of each card) which can be connected to. and each card can have several out joints (on the left and right sides of each card) which can connect to other cards. each answer of a card will related to a out joint. So you need to connect the joints of cards to create the troubleshooting flowchart.
To connect cardsJust drag from the out joint to the in joint then drop.

Note: each in joint can be connected to several out joints. but each out joint can be connected to only one in joint.
To disconnect cardsClick the connection line then click the button "Delete Connection" or from the menu Connection->Delete Connection.
