Building the toolchain

Run make bootstrap and wait, it will build the hosted toolchain, ported software, and mlibc.

Building the OS

Typically you'll want to either run make clean run-linux or make clean debug-linux. You can optionally add KVM=1 at the end for faster emulation if your system supports KVM, and SMP=X where X is the amount of virtual CPUs you want it to use.
