 Gila is a Rust microkernel OS, inspired by the Xinu embedded OS, as well as Linux. I aim to implement multitasking and different users for processes, and eventually a filesystem. I do not aim to make it POSIX-compatible, but it will likely end up sharing many features with POSIX operating systems.

+### Features
+
+Gila has four optional features, which I made optional in anticipation of a potential future port to older systems like i686 which might not support modern standards like UEFI or ACPI. They are all enabled by default. Disabling them reduces kernel size and forces the kernel to fall back to other implementations for some functionality like device discovery.

 ## Kernel Parameters
 
 Kernel parameters are passed as part of the `cmdline` through [limine.conf](limine.conf). The parameters are passed as a space-delimited list of keys and values. Keys begin with a hyphen (`-`), and keys are separated from their values with equals signs (`=`). Keys can have a set of multiple values, separated by a comma (`,`). Gila does not currently support parameter values with spaces. That would require an *actual* parser.
