I got this itch too when I came across tinyrenderer [1] and worked through the early lessons through shading, but didn't quite finish the texture mapping yet [2]. It was fun to work in pure C from first principles, even side-questing to write a simple TGA file reader and writer.
I'd be very interested to see your tutorial when it's done!
Personally, I'd love this is if it were opt-in. That way, I could gradually reduce my repeat search dependence based on me recognizing my actual habits, rather than giving a browser extension carte blanche access to my entire search history. Maybe that's already possible, but I didn't see any documentation about the config file.
