-# libk is for the code that did not make the kernel*
-
-\*crate, lol.
-
-libk is an attempt to move away from the godforsaken git submodules that plagued our forefathers. Now we have a crate containing a bunch of code that didn't quite make the core kernel crate, which should be:
-
-* simpler to maintain
-* has a catchier name
-* less fighting with Cargo.toml manifests
-
-## TODO:
-
-A lot of things must be improved and worked on, feel free to add extra TODOs below.
-
-[] Create a kernel logging abstraction similar to Linux. (this should probably just use the serial drivers)
-
-The rationale behind this is that we want some sort of debug log/tracing support so we aren't just printf debugging forever.
-
-## Authors
-
-Again, write your name below if you like:
-
-* @zxq5 (wrote most of the libraries as of 23/02/25)
-* @nullndvoid (made this lushious library crate)
