 Zorya NEO is the successor to the Zorya 1.x series of BIOS+Bootloaders for OpenComputers. It's design is now much more modular and extendable.
 
 ## How do I begin?
-wait till it's stable and i release a zorya-neo-installer cpio
+Grab the latest release. Install the BIOS before the utilities. The install is self-extracting. Don't download the tsar.
 
 ## How do I configure it?
-Edit /.zy2/cfg.lua
+Edit /.zy2/cfg.lua or use the OpenOS config generator.
 
 ## What modules/libraries are included by default?
-* Microtel (`krequire "net_minitel"`)
+* Multithreading (`krequire("thd")`)
-* Zorya LAN Boot 2.0 (`krequire "util_zlan"`)
+* TSAR archive reader (`krequire("util_tsar")`)
-* Classic Zorya Menu (`loadmod "menu_classic"`)
+* CPIO archive reader (`krequire("util_cpio")`)
-* Threading library (`krequire "thd"`)
+* URF archive reader (`krequire("util_urf")`)
-* Virtual Devices library (`loadmod "util_vdev"`)
+* Romfs archive reader (`krequire("util_romfs")`)
+* Minitel networking (`krequire("net_minitel")`)
+* vComponent (`krequire("util_vcomponent")`)
+* OEFIv1 (`loadmod("util_oefiv1")`)
+* OEFIv2 (`loadmod("util_oefiv2")`)
+* OpenOS loader (`loadmod("loader_openos")`)
+* Fuchas loader (`loadmod("loader_fuchas")`)
+* vBIOS (`loadmod("vdev_vbios")`)
+* Search paths configuration (`loadmod("util_searchpaths")`)
+* BIOS info component (`loadmod("vdev_biosdev")`)
+* VFS (`loadmod("vfs")`)
+* Zorya classic menu (`loadmod("menu_classic")`)
+
+## What's the difference between modules and libraries?
+There's not really a hard difference. But libraries shouldn't load modules. Modules can load libraries, though.

+Loading libraries is done with `krequire`. Be careful of this. Also, you have to load modules through the `zorya` library. Also, uncaught thread errors will crash the system. Be mindful of that.
