When the program is started, the user is presented with a minimal pedigree consisting of a father, a mother and a child. On the left of the screen there is a slider for zooming in and zooming out.
In the top left corner three buttons can be seen, two of them (undo and redo) are greyed out. The third button is for downloading the pedigree.
In the top right corner two buttons can be seen, the left one (drawing view) is selected. By clicking the right button, the table view is selected.
At the bottom of the screen there is a link for uploading a previously saved pedigree file.
To select a person, click on the icon. The icon is now coloured red. In the panel on the right, the attributes of the individual can be modified. Additional attributes can be added by clicking the pencil icon. After editing the attributes, click Save fields to apply the changes.
Selecting a person also adds two additional buttons (Add partner and Add parents) to the top of the screen. If the selected person has parents, a third button (Add twin) will appear.
Click on the vertical line that is perpendicular to the line connecting two partners to select a relationship. This will add the button Add child in the upper left corner.
