Hmm, well, you have a point there. I guess I just figured there might be more useful resources out there that could be added if/when they're found, but that might be a bit preemptive.
An argument could probably be made for putting it in the Language section, but it would probably be more convenient at the bottom like you suggested.
I've found another resource, though this one isn't a website. The OpenGL SuperBible, Third Edition has three chapters pertaining to ARB shaders (20, 22, and 23). It may be difficult to find a physical copy these days, but it can be viewed on the Internet Archive: https://archive.org/details/open-gl-superbible-3rd-edition_202207
It can also be found (in a .rar with the example code included) on a certain website that I probably shouldn't name or link here because it's probably against itch.io's ToS, but which is known for hosting a vast collection of books in various formats.
