About the Pavlovia Manual

Dear friends,
I am trying to publish the PsychoPy experiment using Pavlovia, but I can not find the complete manual which can tell me how to achieve one step by one step.
Could you please to offer the manual or some useful website?
Thank you very much for your patience.

Yours sincerely,
Yi Tian

@krong2020, a good start is the online documentation on the website: https://www.psychopy.org/online/index.html
