The self-taught course requires no registration other than this forum registration which you already did.
The materials are available from
http://www.nand2tetris.org/, including the textbook chapters 1-6 and appendices. This covers the hardware aspects of the course and writing the Assembler.
Chapters 7-12 deal with higher-level software tools. All the source materials including lecture slides are available on the web site, but you will probably want to buy a copy of the book to understand the details.
