as above – stick with it you’ll get the hang of it
tamping is a bad idea
You will work out the best combination of amount of coffee to use/ heat setting on the hob etc
Personally with my 3 cup pot (I drink all of it of course) I fill with water from the tap up to the line, 2 x spoons of beans which i then grind resonablly fine (not as fine as you would for a proper espresso machine, finer than caffitierre or filter). coffee in, no tamping.
On the hob at heat setting 4 out of a possible 6.
I actually prop open the lid with a teaspoon so I can see the coffee coming through and get the pot off the heat as soon as it begins spurting.
