Installation of CATIA 2024x Refresh1

Hello, 

i got the installation files for the new Release (2024x Refresh1) for MCSE. I downloaded 3 Zips files (see picture below). My question is about the "DOC_CAT" zip file containing documentation in PDF format. Which is the porpouse of this Zip? Should i Install it, or just copy in the "MCSE Installation folder\Manual" or what? 

Many thanks
