How do I edit this? Thanks for your help!

Hi everyone,

I'm a newbie here :) I'm editing a video and I would like there to be text appearing "letter for letter" just as if it was written. Basically exactly like in this video:

Also I really like this hand written font.

Does anyone knows how to do this? I have no experience whatsoever with video editing and this would be my first try with editing a video but if anyone can help me with giving advise on how to create this effect, I would be very grateful.

Thanks again! Rose
