The instructions at https://webwork.maa.org/wiki/Category:Release_Notes say:

"If you are tracking the master branch, then the command

     cd /opt/webwork/webwork2
git pull


will update your code base. Similarly for the pg and library code."

This is somewhat enigmatic! Exactly what are the actual cd and other commands to update the pg and library code??
