+[[!meta title="Setting up a ProteanOS Package Development Environment"]]
+
+This guide will explain how to set up a ProteanOS development system for
+building software packages under chroot.
+
+Note that to build packages under chroot you need a system running Linux 3.4 or
+later.  These instructions have been tested on a Debian GNU/Linux 7.0 (wheezy)
+system with Linux 3.12 from wheezy-backports.
+
+The ProteanOS Development Kit uses the **chroot**(8) and **mount**(8) commands,
+which on Linux require superuser access.  This guide assumes the use of
+**sudo**(8) for running commands with superuser privileges.  Adjust where
+necessary if you don't use **sudo**(8).
+
+
+Installing the ProteanOS Development Kit
+========================================
+
+First you'll need to get prokit, the [[ProteanOS_Development_Kit|dev/prokit]].
+This toolkit can install a ProteanOS system, run a ProteanOS shell and other
+commands, manage software packages on an installed ProteanOS system, and build
+packages for ProteanOS (with build dependencies automatically installed and
+removed).
+
+Ensure you have a **make**(1) utility such as GNU Make installed.  No C or C++
+compiler or other development tools are necessary to build prokit.
+
+Download a released version of prokit from the files site by HTTP or FTP, e.g.:
+
+    $ wget http://files.proteanos.com/pub/prokit/1.0.0-beta1/prokit-1.0.0-beta1.tar.gz
+    $ tar -xzf prokit-1.0.0-beta1.tar.gz
+    $ cd prokit-1.0.0-beta1/
+
+Or clone it from the [Git repository][prokit-git]:
+
+    $ git clone git://git.proteanos.com/prokit/prokit.git
+    $ cd prokit/
+
+Configure and build prokit:
+
+    $ ./configure
+    $ make
+
+It is recommended but not necessary that you install prokit to your system:
+
+    $ sudo make install
+
+Check that the installation was successful:
+
+    $ prokit version
+
+Or, if you didn't install prokit, run:
+
+    $ src/prokit version
+
+Refer to the **prokit**(1) manual page:
+
+    $ man prokit
+
+Or, if you didn't install prokit, run:
+
+    $ man man/prokit.1
+
+[prokit-git]: http://git.proteanos.com/prokit/prokit.git/
+
+
+Install a ProteanOS Development System
+======================================
+
+Now you can install a ProteanOS system into a directory in your file system.
+
+Decide where to install ProteanOS and run:
+
+    $ sudo prokit install dev/trunk $root
+
+`$root` is the directory you chose.
+
+You may see some warnings such as:
+
+    prokit: Warning: root/var/lib/opkg/lists/proteanos_dev_trunk_i686-linux-glibc_all_base(l324): badly formatted control field
+    prokit: Warning: root/var/lib/opkg/lists/proteanos_dev_trunk_all_all_base(l689): badly formatted control field
+    prokit: Warning: root/var/lib/opkg/lists/proteanos_dev_trunk_all_all_base(l709): badly formatted control field
+    prokit: Warning: root/var/lib/opkg/lists/proteanos_dev_trunk_src_all_base(l310): badly formatted control field
+
+This is an issue in opkbuild which has been [fixed in the Git
+repository][ob-gencontrol-bug] and will be fixed in ProteanOS soon.  It can
+safely be ignored.
+
+Next install all of the toolchain packages commonly used to build ProteanOS
+packages:
+
+    $ sudo prokit shell $root 'opkg install build-essential-$(cat /etc/proteanos_arch)'
+
+This may take a while, depending on your network connection.
