I liked Graf Martinez method book. Helped me understand basics. I'm an average guitar player and finished basic music school.

You should know some notation and basic musical theory.

Also like in general, it will benefit you if you have some rhythmic and melodic talent.

Flamenco has a bit complex basic forms. But when you understand them you can play around.

Unusual chords and irregular rhythms, often syncopated shapes. Right hand is a technique of it's own.

Average musician can learn some basic forms to play around.

Advanced flamenco is a lot harded, that's virtuoso stuff.

It's probably a bit too much to grasp at the begining of learning music, but it could be done.
