Well, Howdy, Dave
First of all, congratulations on getting your first, and if you're new to this forum, Welcome!
Filling is easy, if you have a bottle of ink. You ...
Dip the point into the ink past its breather hole,
With the point immersed in the liquid, raise the lever from the end with your finger nail until it's about perpendicular with the barrel (don't force it too far), then
Lower the lever back until it's flush with the barrel and keep the point immersed for about 10 seconds. You should maybe hear some kind of sucking sound as the rubber sac inside the barrel draws in the ink.
Repeat the above one or two times if desired (I just do it once).
Remove the point from the ink, wipe off any excess ink that may have gotten onto the section, and you're ready to write.
That's about it. As you get used to the activity, you'll develop your own way of doing it easiest for yourself. If you dip it too far, no problem, it'll still fill up OK. Just wipe off the excess ink.
Hope I got your question right, and that this helps. If not, let me know.
Edit: As I look back, I forgot to mention ... Yes, it does fill through the breather hole in the point.
