Anyway, I was going to write the next part but I realized that this not gonna as you said people use audio-video content. So better to provide good references rather than explain all in content. For the Sources dear I am not using Imgaes and also the whole content is a type of summary of my learnings so I can't point out the sources.
On the contrary, the topic is easy, any information you learned, open Notepad and leave the link there, when there are a lot of references in your topic, it is more valuable than a topic rather than a reference.
All in all, don't give up, you're off to a good start and a little help will make your placement perfect.
The most important thing is not to stop.
