 Homebrew 32bit computer
 =======================
 
+About
+-----
 Following after my minimal 16bit 68010 computer design
 (https://github.com/jtsiomb/m68kcomputer) this is an attempt to make a much
 more advanced 32bit computer, based on the Motorola 68030 CPU.
 
-The main objective of this project is to make a stand-alone computer capable of
-running a custom UNIX system, with virtual memory.
+The main objective of this project is to make a stand-alone computer, capable of
+running a custom UNIX system with virtual memory. The 68030 processor was chosen
+because it has an on-chip MMU.
+
+The plan is to include the following on the main board:
+ - Analog video output
+ - PS/2 keyboard controller
+ - ATA hard drive interface for fixed storage
+ - SD card for removable storage
+ - 68881 floating point co-processor
+ - Dual RS232 serial port
+ - Battery-backed RTC
+
+This project is in the early stages, so there's not much to see here yet.
+
+Directory structure:
+ - `hw` - hardware: kicad files and pdf schematics.
