Default [Q] Which instructions for porting CWM Recovery are correct?

I am going crazy trying to port CWM Recovery to my device, a Japanese Galaxy S3 (SCL21). I have been using these instructions and have yet to create a successful build.

I also found these instructions

Which of these is correct? They both say to edit recovery.fstab which is fine, but the former also tells you to edit If it is indeed necessary to edit, is there some kind of barebones config if we only need a recovery image?
