Official language tutorial series.

Someone, may be a even GB himself, should take time to write a complete step by step guide for the newbies. Like the one Nim has for example: https://nim-lang.org/docs/tut1.html
The tutorial topic does't really matter here, but I think some graphical application on SDL3\OpenGL\Vulkan\WGPU API from start to finish would be the best choice, since Odin has really cool built-in matrix operations. It has to take into account real word situations and be low level enough to learn from it.
The easiest solution will be to take https://github.com/Capati/odin-vk-guide (If the author don't mind it ofc), finish the bonus chapters and maybe refactor some old ones to explicitly use Odin tricks and features. It will be a cool demonstration for the newcomers what they can achieve, like saying "you think Vulkan is scary? Look how it is easy with Odin now!" Well, maybe not really "easy", but rather "enjoyable" - I hope you get the idea.
