## Other Rust OS Projects
Now that you know the very basics of OS development in Rust, you should also check out the following projects:
- [Rust Bare-Bones Kernel]: A basic kernel with roughly the same functionality as ours. Writes output to the serial port instead of the VGA buffer and maps the kernel to the [higher half] \(instead of our identity mapping).
