While studying Hansteen's book is a good choice, note that it was published in 2010. Work on
pf(4) has continued. Studying this book
and studying the
PF User's Guide (which is always current...) is strategically a better choice.
Also note that Hansteen's
PF manuscript continues to be updated. The latest set of changes is dated June 2013.
Studying all three documents will help fill in any blanks found in any one particular source.
