These instructions explain how to install ProteanOS into a directory on an
existing host system to run under an isolated file system environment, or
"jail", using prokit, the ProteanOS Development Kit.  prokit will run ProteanOS
using the **chroot**(2) system call via the **chroot**(8) wrapper program.

It is assumed that you have already

Installing ProteanOS
====================

First decide which "suite" of ProteanOS you wish to install.  `rel/trunk` is a
rolling release that receives updates free of known new bugs; it is recommended
for regular users.  `dev/trunk` receives direct package uploads and should be
used by ProteanOS developers.

Next decide where to install ProteanOS.  Replace `$root` below with the path to
which you want ProteanOS installed.

If you installed prokit to your system, simply run:

    $ sudo prokit install $suite $root

Otherwise, from your prokit build directory, run:

    $ sudo ./prokit install $suite $root

Next Steps
==========

Familiarize yourself with the ProteanOS Development Kit Manual, if you haven't
already.  The **prokit-shell**(8) and **prokit-opkg**(8) commands are used to
manage installed ProteanOS systems.

If you'd like to develop packages for ProteanOS, you need to install the
`build-essential` package (again replacing `prokit` with `./prokit` if you
haven't installed prokit):

    $ sudo prokit opkg $root install build-essential
