Hi suziq
All genealogical software can import a GEDCOM file and can print various reports/charts. You may need to study the Heredis help file in more detail.
I assume there will be an item labelled File on the top left hand side of the screen and you click on that and scroll down to an item labelled Import?
You will then have to specify the format or type of file i.e. GEDCOM and then specify the path or where the gedcom file is located.
