@Canuckistan Maybe this is a good project for you? While learning Obsidian, write everything down you learned in a way that you would understand it.
Now you probably ask, “how you can learn if there is no such material”?
Well, simply start with the help vault that is shipped with Obsidian (click on that question mark icon on the bottom left). Then go through every page of explanation. If there is anything that you don’t understand, write it down (in Obsidian) and try to find the answer first by simply playing around with Obsidian (learning through play is the best and most fun way to learn) and then if you can’t figure it out, by asking on this forum or the Discorse chat. If you ask concrete questions, people will give you concrete answers. (But search the forum first, since many questions have been asked many times and answered many times already.) Then write that answer down as well (in Obsidian), in your own words. In the process of learning Obsidian that way, you will also have created an “Obsidian for dummies” vault that you can publish for the next learner.
In parallel, try to understand Markdown. It is fundamental to Obsidian, and without understanding it you won’t get anywhere. Luckily, Markdown is very simple (that’s the whole idea behind it - to be vey simple), and there are already many tutorials online - e.g. here and here and here.
Another tipp: Don’t try to understand everything in the beginning. Don’t try to understand how to make a theme or a plugin or even block level links. Start with the basics, as they are explained in the help vault. Then if you mastered that, re-visit the forum and Youtube for learning more advanced stuff. Try to learn step by step. If you really like watching videos instead of learning by doing, start with very simple ones, like the one suggested by @tav.
Please understand that it is very hard for power users of Obsidian to write “for dummies” tutorials. First, it is very hard for them to imagine the kind of questions dummies may have on their minds. Second, it is very boring for them to write down such (for them) basic stuff. So I think it is best for you to take things into your own hands. This way you will soon become a power user too.
