How to develop?

Hi there,
first tnx for this great tool ankulua.
i've installed IntelliJ IDEA + Lua plugin.
i want to start coding my own script.
i am trying to understand the coding method:

i writing my script on the IDEA and then i should copy (or sync) it to my mobile device and run it from there?

if so, is it possible to run and debug in real time?

i hope i could explain myself,
appreciate your  help,
tnx Assaf
