First, make sure FreeBSD is installed and your jail is setup correctly:

Then, follow the directions here to build your first images with m0n0dev:
http://www.askozia.com/code/m0n0wall/m0n0dev.php#getting-started

Currently, m0n0dev is just a fancy Makefile.  As more needs arise in
my project, I will add and release those features (i.e. image
mounting).
