The GARLI Manual consists of these components
Using the MPI version (not in pdf manual)
FAQ (some information not in pdf manual)
Advanced topics and tutorial (not in pdf manual)
Manual in pdf format
Alternatively, you can download the manual in pdf format from here. (Scroll down to "Available Packages" and choose "Manual for Version 0.96"). Note that the information on the wiki is more up to date than that in the pdf manual. I suggest that you use the online resources and do not waste paper by printing the manual.
