Creating textbooks for specific courses on khan academy

Hello,  my name is Nikhil Saini. I am a high schooler and like millions of other students, I have found Khan Academy a lifesaver in tests and prepping for APs.  I want to propose the idea of making online textbooks explaining the content in a different way than usual. These textbooks would be completely free and complement the videos made. I currently have a good structure for the textbooks and a good idea for algebra, algebra 2, precalculus, and calculus. If given the opportunity, I will make the textbooks as aligned with the videos as possible. This would also align with schoolhouse.world giving teachers another resource to help teach the students. As a part-time schoolhouse tutor, I feel it would be very helpful to have a textbook to use as a reference. If you are interested in furthering the development of these textbooks please let me know. Thank you and have a great rest of your day.
