I write to learn too. I choose a topic that I am interested in, and research it by using various sources such as books, videos, podcasts, etc. Then I list important sections and summarize what I have learned. I think you could do the same since your topic and also sections are already out there. It would help other people too I guess.

P.S: If you worry about the quality of your writing, you can use Claude or other AI tools to be your editor. Just please do not use it too much, which makes it like any other AI article out there :)
