12The Makefile in this directory supports a number of targets for
13building components (or all) of the FreeBSD source tree.  See build(7)
14and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/makeworld.html
15for more information, including setting make(1) variables.
16
17The `buildkernel` and `installkernel` targets build and install
18the kernel and the modules (see below).  Please see the top of
19the Makefile in this directory for more information on the
20standard build targets and compile-time flags.
21
22Building a kernel is a somewhat more involved process.  See build(7), config(8),
23and https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/kernelconfig.html
24for more information.
25
26Note: If you want to build and install the kernel with the
27`buildkernel` and `installkernel` targets, you might need to build
28world before.  More information is available in the handbook.
29
30The kernel configuration files reside in the `sys/<arch>/conf`
31sub-directory.  GENERIC is the default configuration used in release builds.
32NOTES contains entries and documentation for all possible
33devices, not just those commonly used.
