I have a "mini-guide" for Silk 2 if you call it that (it's a collection of two discord messages), but I don't think there are any guides for Silk 3.
I had to figure it out on my own back when I started on the Vulkan bindings last year.
Once I get started on new Silk 3 bindings, the PR diffs for those bindings should serve as a good reference before a full guide is written.
Also, I don't think Silk 3 and Silk 2 can be used in the same project right now so using Silk 3 (which isn't in preview yet) might not be a great idea outside of experimentation.
