-An experimental Multiboot 2 crate for ELF-64 kernels. It's still incomplete, so please open an issue if you're missing some functionality. Contributions welcome!
+Library that helps you to parse the multiboot information structure (mbi) from
+Multiboot2-compliant bootloaders, like GRUB. It supports all tags from the specification
+including full support for the sections of ELF-64. This library is `no_std` and can be
+used in a Multiboot2-kernel.
 
-It uses the Multiboot 2.0 specification at https://www.gnu.org/software/grub/manual/multiboot2/multiboot.html and the ELF 64 specification at http://www.uclibc.org/docs/elf-64-gen.pdf.
