+.Sh NAME
+.Nm autoinstall.conf
+.Nd automatic installation configuration
+.Sh SYNOPSIS
+.Nm /etc/autoinstall.conf
+.Sh DESCRIPTION
+.Nm
+configures
+.Xr sysinstall 8
+to do an automatic operating system
+.Xr installation 7 .
+.Pp
+The system administrator can automate operating system installations by
+following
+.Xr release-iso-modification 7
+to embed the
+.Pa /etc/autoinstall.conf
+file into the release cdrom filesystem.
+Existing installations can similarly be automatically upgraded using
+.Xr autoupgrade.conf 5 .
+.Pp
+Each line is formatted as
+.Ar question Ns = Ns Ar answer
+which provides an
+.Ar answer
+to a
+.Ar question
+asked during installation.
+Alternatively
+.Ar question Ns += Ns Ar answer
+appends to an existing answer (if any) separated by a space, and
+.Ar question Ns ++= Ns Ar answer
+appends another line to an existing answer (if any).
+Empty lines and lines starting with
+.Sq #
+are comments and are ignored.
+Otherwise whitespace is significant.
+The empty answer accepts the default answer (if any) and is different from no
+answer, which makes
+.Xr sysinstall 8
+ask the question normally.
+Installations can be made fully non-interactive using
+.Sy accept_defaults .
+.Pp
+The questions in chronological order are as follows:
+.Bl -tag -width "12345678"
+.It Sy accept_defaults Ns "=" Ns Oo Sy no "|" yes Oc ( default Sy no )
+Accept the default answer (if any) to questions that were not
+configured in
+.Nm .
+This feature makes installations entirely automated even if unexpected questions
+are asked, although the essential questions must be answered.
+.It Sy countdown Ns "=" Ns Ar seconds No ( default Li 10 )
+Count down for this many
+.Ar seconds
+with a warning that an automated installation is about to happen.
+The countdown happens if the
+.Sy ready
+question is answered and either the
+.Sy disked
+or
+.Sy confirm_install
+questions are answered.
+.It Sy ignore_missing_programs Ns "=" Ns Oo Sy no "|" yes Oc ( default Sy no )
+Ignore if the installer environment does not have the needed ports installed.
+This situation ordinarily does not happen.
+ready
+.It Sy ready Ns "=" Ns Ar affirmation
+A human readable positive affirmation of your choice that you're ready to
+install, useful for fully automated installations.
+Not answering this question is useful for semi-automated installations where one
+would acknowledge the installation before it's begun.
+It also provides the opportunity to escape to a shell before installing.
+.It Sy kblayout Ns "=" Ns Oo Sy default "|" Ar layout Oc ( default Sy default )
+Switch to this keyboard
+.Ar layout
+using
+.Xr chkblayout 1 .
+The choice is set as the system default in
+.Xr kblayout 5 .
+.It Sy videomode Ns "=" Ns Oo Sy no "|" Sy yes "|" Ar WIDTH Ns x Ns Ar HEIGHT Ns x Ns Ar BPP Oc ( default Sy yes )
+Interactively select a graphics resolution using
+.Xr chvideomode 1
+or non-interactively set it to the specified resolution.
+The choice is set as the system default in
+.Xr videomode 5 .
