OK, I've installed successfully Delphes and PAM.
It didn't work initially. After digging I was missing some packages on Ubuntu 17.10: libtbb-dev, libtiff-dev, libjpeg-dev and tclsh
I guess we should familiarize ourself with the root primer document?
Knowledge of the root software is not necessary. This is a requirement to run the LHC detector simulator that is integrated to the package (i.e. Delphes).
If you want to get familiarized with the platform, I can recommend this page that should be updated one day... However, the available material is still ok as a starter ;)
