First a person will need to have the latest form of Java installed. Taking the information from this guide, please open terminal and follow these steps. https://www.youtube.com/watch?v=isZaiBq1GC8#t=75

sudo apt-get update
sudo apt-get install oracle-java8-installer -y
For other versions of Linux you can try this tutorial too. https://forum.ournem.com/tutorials/how-to-java-firefox-linux-mintubuntu/
After Java is installed the please go to http://bob.nem.ninja/ and download the latest version of NEM. The file will probably be more than 30M.
Unpack the file to your desktop.
Open terminal and please enter these commands
cd Desktop/package
./nix.runMon.sh
If everything goes well you will see NEM start up.
