Information about disclosure and sale:
Public information: basic knowledge information, in fact, it should be basic + basic extended use
Materials for sale: In fact, the materials for sale are the reintegration and application of basic knowledge. These materials can be used for development and projects, because the source code of the materials I developed can be directly used.
Earn money for others, shorten the time for others to develop projects and save costs, so I chose to charge for this part (even for the materials sold, all the video and video tutorials will be published, thank you for your support!)
About the later stage:
I expect that at some point in the future I will release all the information, and I am also looking forward to this point in time. Thank you for your support
