Hey Erth, cool that you are trying it out! Reading the op I feel like you should underline how time consuming it actually is. Scheduling a session is the most complicated part since everyone has different lives and times, so you should have clear ideas of when and how many times are going to meet, plus combining that with a certain range of GMT. Be careful about how you choose your players or the story might end before it starts.
That said, I've a bit of DMing experience in DnD 3e (30 sessions in an homebrew campaign that is still going) so if you want some advices feel free to ask. DMing can be quite daunting, I remember very well my first times.
Btw, I don't know how experienced of a player you are, so you probably already know all of this ahah.
