Thank you so very much for writing it! I always assumed bokeh and other camera tricks were very difficult to master, but your tutorial made me realize that anyone with a basic understanding of camera optics (and hopefully also owning a DSLR camera) can do it!!! You are the best
I think you should add a note/change the introduction a bit. Let readers know that they should have access to a DSLR (borrow from mom/dad etc.) or else most of the information won't make sense.
