28.Dt DEVELOPMENT 7
29.Os
30.Sh NAME
31.Nm development
32.Nd introduction to
33.Fx
34development process
35.Sh DESCRIPTION
36.Fx
37development is split into three major suprojects: doc, ports, and src.
38Doc is the documentation, such as the
39.Fx
40Handbook.
41To read more, see:
42.Pp
43.Lk https://www.FreeBSD.org/doc/en/books/fdp-primer/
44.Pp
45Ports, described further in
46.Xr ports 7 ,
47are the way to build, package, and install third party software.
48To read more, see:
49.Pp
50.Lk https://www.FreeBSD.org/doc/en/books/porters-handbook/
51.Pp
52The last one, src, revolves around the source code for the base system,
53consisting of the kernel, and the libraries and utilities commonly called
54the world.
55.Pp
56The Committer's Guide, describing topics relevant to all committers,
57can be found at:
58.Pp
59.Lk https://www.FreeBSD.org/doc/en/articles/committers-guide/
60.Pp
61.Fx
62src development takes place in the CURRENT branch in Subversion,
63located at:
64.Pp
65.Lk https://svn.FreeBSD.org/base/head
66.Pp
67There is also a read-only GitHub mirror at:
68.Pp
69.Lk https://github.com/freebsd/freebsd
70.Pp
71Changes are first committed to CURRENT and then usually merged back
72to STABLE.
73Every few years the CURRENT branch is renamed to STABLE, and a new
74CURRENT is branched, with an incremented major version number.
75Releases are then branched off STABLE and numbered with consecutive minor
76numbers.
77.Pp
78Layout of the source tree is described in
79.Xr hier 7 .
80Build instructions can be found in
81.Xr build 7
82and
83.Xr release 7 .
84Kernel APIs are usually documented, use
85.Ql "apropos -s 9 ''"
86for a list.
87Regression test suite is described in
88.Xr tests 7 .
89For coding conventions, see
90.Xr style 9 .
91.Pp
92To ask questions regarding development, use the mailing lists,
93such as freebsd-arch@ and freebsd-hackers@:
94.Pp
95.Lk https://lists.FreeBSD.org/
96.Pp
97To get your patches integrated into the main
98.Fx
99repository use Phabricator;
100it is a code review tool that allows other developers to review the changes,
101suggest improvements, and, eventually, allows them to pick up the change and
102commit it:
103.Pp
104.Lk https://reviews.FreeBSD.org/
105.Sh EXAMPLES
106Check out the CURRENT branch, build it, and install, overwriting the current
107system:
108.Bd -literal -offset indent
109svnlite co https://svn.FreeBSD.org/base/head src
110cd src
111make -j8 buildworld buildkernel installkernel
112reboot
113.Ed
114.Pp
115After reboot:
116.Bd -literal -offset indent
117cd src
118make -j8 installworld

128.Sh HISTORY
129The
130.Nm
131manual page was originally written by
132.An Matthew Dillon Aq Mt dillon@FreeBSD.org
133and first appeared
134in
135.Fx 5.0 ,
136December 2002.
137It was since extensively modified by
138.An Eitan Adler Aq Mt eadler@FreeBSD.org
139to reflect the repository conversion from
140.Xr cvs 1
141to
142.Xr svn 1 .
143It was rewritten from scratch by
144.An Edward Tomasz Napierala Aq Mt trasz@FreeBSD.org
145for
146.Fx 12.0 .
