Ugh...I need to engrave plastic nameplates and have never used a mini computer controlled 3020T DJ router engraver machine or Mach3 ever!!!!! I am completely clueless

My boss purchased these products, and unfortunately, is under the impression that this is a "plug and play" process. No one here in our office can operate this... Is there a simple way to engrave text with this software or is there other software I am needing to purchase? Perhaps there is "Mach3 for Dummies". I have spent the last 3 days at work stressing over this and need serious help. Any advise anyone can spare would be greatly appreciated. All I can say at this point is THANK GOD IT'S FRIDAY!!!!
