 ## 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).

 _Note_: You need to [cross compile binutils] to build it (or you create some symbolic links[^fn-symlink] if you're on x86_64).
