## Documentation
Initially, syzkaller was developed with Linux kernel fuzzing in mind, but now
it's being extended to support other OS kernels as well.
Most of the documentation at this moment is related to the [Linux](docs/linux/setup.md) kernel.
For other OS kernels check:
[Darwin/XNU](docs/darwin/README.md),
[FreeBSD](docs/freebsd/README.md),
[Fuchsia](docs/fuchsia/README.md),
[NetBSD](docs/netbsd/README.md),
[OpenBSD](docs/openbsd/setup.md),
[Starnix](docs/starnix/README.md),
[Windows](docs/windows/README.md),
[gVisor](docs/gvisor/README.md).
