+- `KiCad` contains the design files for the Cody Computer's electronics.
+- `OpenSCAD` contains the design files for the Cody Computer's printable parts.
+- `STL` contains the generated STL files suitable for slicing and printing.
+- `Spin` contains the Propeller `.spin` files for the Propeller's firmware.
+- `Tass` contains the `64tass` assembly files for Cody BASIC and demo programs.
+- `CodyBASIC` contains some sample Cody BASIC programs used for demo purposes.
+ 
+All design files and sources are released under the GPL version 3. The
+Cody Computer Book included with the sources is not but may be freely
+distributed. 
+
+Note that the book is still in draft form and updates will be made to
+the repository in the future.
