-### 2. Build source.
+### 2. Building on unix-like platforms
+You'll need Lua installed. It will probably work with anything from 5.1 onwards, but PsychOS is developed against 5.2.
 
 ```
 ./genkernel.sh
 ```
 
-`genkernel.sh` is a wrapper script for genkernel.lua which is a wrapper program for the genkernel module that is actually used to generate the code.
+`genkernel.sh` is a wrapper script lmk that generates all the kernel configurations in config/ and places them in out/.
 
-To change the modules included, modify build.cfg.
+Naturally, you can modify the configuration files or add new ones to change the modules included.
 
 ## Building on PsychOS
 ### 1. Obtain source and relevant software.
-At present, the way to do this is "copy them onto the installation."
+**TODO: Write package recipes for the sources**
 
-If genkernel() isn't included in your kernel you can run it as a program using luash's ! prefix.
-
-### 2. Run genkernel()
+### 2. Build with lmk
+lmk is the Lua MaKe system used for PsychOS. The sources come with makefiles that you can use to generate a kernel.
 
 ```
-genkernel("/boot/PsychOS/build.cfg","custom")
+cd kernel_source_dir
+lmk configs/everything.lua
 ```
 
-This will generate a kernel from the files listed in /boot/PsychOS/build.cfg with "custom" as part of the kernel name and return the resulting kernel as a string. You can then write that string to a file or similar.
+This will build the "everything" kernel. You can use a different configuration file if you want to generate another kernel.
 
-## Files
-### genkernel.sh
-genkernel.sh calls `genkernel.lua build.cfg`.
-### genkernel.lua
-Wrapper for modules/applications/genkernel.lua. Runs it with arguments.
-### modules/applications/genkernel.lua
-Both a PsychOS module and usable as a program.
-#### genkernel(*bp*, *kn*)
-Builds a kernel using the modules listed in *bp*, with \_OSNAME including *kn*.
+You can then try loading the new kernel to check for errors:
+
+```
+=loadfile("out/everything.lua")
+```
+
+If there are no errors, it's probably safe to move it to your /boot/init.lua.
