[ubuntu] Cannot install Libre Office

http://ubuntuforums.org – The readme on how to install LibreOffice says this: "This directory contains a subdirectory called "DEBS". Change directory to the "DEBS" directory. Right-click within the directory and choose "Open in Terminal" " however when I open the DEBS folder and right-click i don't see any option called 'open in terminal' also, it asked me to do all this in 'file manager' and to 'change directories' and stuff like that I dont know what changing the directory is and is the file manager the home folder? BTW i HAVE gotten rid of the old version of Libr (Hardware)
