-# Installing PsychOS
-
-## From OpenOS
-### Requirements
-In general:
-- oppm
-- mtar
-
-For installing to an unmanaged drive or tape
-- slicer
-- partman
-- rtfs
-- boopu
-
-There are two easy methods to get these packages.
-1. With oppm, if available, you can run `oppm install mtar partman rtfs boopu`.
-2. You can use the `obootstrap.lua` script to set up a temporary environment for installing PsychOS. This can even be used from the OpenOS installer disk.  
-```
-# wget https://git.shadowkat.net/izaya/OC-PsychOS2/raw/branch/master/obootstrap.lua /tmp/obootstrap.lua
-# /tmp/obootstrap.lua
-```
-
-### Preparing the target disk
-#### Managed filesystem
-Preparing a managed filesystem is extremely simple: attach it to your computer, and make sure there's nothing that you want to keep in the following locations on the filesystem:
-- init.lua
-- lib/
-- service/
-- doc/
-- pkg/
-- cfg/
-
-#### Unmanaged drive or tape
-##### Creating partitions
-First, you'll need to find out how many sectors your target device has. `slicer <addr> show` will show you something like this:
-
-```
-# slicer 9f7 show
-Drive 9f755736 - 1024KiB, 2048 sectors:
- #  Name                 Type Start   Len   End
-```
-
-The usable space on the disk is going to be two sectors less than the total size - sectors 2 through 2047, in this case, as you will want to leave space for the OSDI partition table at the start, and the MTPT partition table at the end.
-
-First, we'll create the boot partition. 64KiB is the recommended size, though 48KiB may be enough. OC disks use 512 byte sectors, so that will work out to 128 sectors.
-
-```
-# slicer 9f7 add init.lua boot 2 128
-Drive 9f755736 - 1024KiB, 2048 sectors:
- #  Name                 Type Start   Len   End
- 1: 9f755736             mtpt     0     0    -1
- 2: init.lua             boot     2   128   129
-```
-
-Next, we need to create an rtfs partition, for the boot filesystem. This can use the rest of the space on the disk, but should be named `<first 8 characters of computer address>-boot`.
-
-```
-# slicer 9f7 add ffa5c282-boot rtfs 130 1918
-Drive 9f755736 - 1024KiB, 2048 sectors:
- #  Name                 Type Start   Len   End
- 1: 9f755736             mtpt     0     0    -1
- 2: init.lua             boot     2   128   129
- 3: ffa5c282-boot        rtfs   130  1918  2047
-```
-
-Once you're all done, you can restart partman and it should recognise the new partitions.
-
-```
-# rc partman restart
-# components part
-partition       9f755736-a739-4f45-8c5c-35a66a7f5dbe/2
-```
-
-##### Formatting the filesystem
-Next, we'll use the mkfs.rtfs utility to format the filesystem partition we just created. Do note that the order of components is not fixed, so using a shortened version can result in unreliable behavior, like, for example, formatting the boot partition.
-
-```
-# mkfs.rtfs 9f755736-a739-4f45-8c5c-35a66a7f5dbe/2 ffa5c282-boot
-9f755736-a739-4f45-8c5c-35a66a7f5dbe/2
-```
-
-To make OpenOS mount the filesystem, the simplest way is to restart partman again, as described in the previous section.

README.md

@@ -6,31 +6,23 @@ A lightweight, multi-user operating system for OpenComputers
 
 ### The kernel
 
-The kernel is composed of a number of modules, found in the *module/* directory, as specified by a file in the *kcfg* directory, `base` by default. Which modules are included can be customised by changing the include statements in the kernel configuration file; copying it and customizing that is recommended, so you can *git pull* later without having to stash or reset your changes.
+The kernel can be built using luapreproc:
 
-#### Unix-like systems
+    ./luapreproc.lua module/init.lua kernel.lua
-
-The kernel can be built using the preproc library and provided scripts:
-
-    lua build.lua kcfg/base.cfg kernel.lua
-
-#### PsychOS
-
-The kernel can be built from inside PsychOS using the preproc library, assuming you have the kernel source available:
-
-    preproc("kcfg/base.cfg","kernel.lua")
 
 ### The boot filesystem
 
 A boot filesystem contains several things:
 
  - The kernel, as init.lua
+ - The exec/ directory, as this contains all executables
  - The lib/ directory, containing libraries
  - The service/ directory, containing system services
- - The exec/ directory, containing single-shot executable files
 
 This has been automated in the form of build.sh, pending a real makefile.
 
 ## Documentation
 
-Documentation is generated as the system is built with build.sh; a set of markdown files will be placed into *doc/*, as well as an all-in-one *apidoc.md*. If pandoc is installed, an *apidoc.pdf* will also be generated.
+To generate function documentation, run:
+
+    ./finddesc.lua module/* lib/* > apidoc.md
