Sure, add a Readme which explains the core design of the OS. Clearly attribute other peoples work you copied or got inspired on (like tutorials). Even if this sounds minor, it will show that you actually engaged with 3rd party resources and maybe did something on your own. This is what would make this project more than just a hacked together experiment with a few bolts on.

Also, people commonly do not share their experiments, except if they are doing something really groundbreaking new. There is a difference of what people do alone in their home, and what they share as a public, at least a bit polished, release.

If you could add a spin of why you feel like your mess is worth it (like you just getted starting coding with this and learn along the way), there would be another reason to engage with it, except to criticize it.
