=== Setting up the Yambo Quantum Machine ===
In order to get the yambo code in your machine you have multiple options:
The tutorials will be run on a dedicated Quantum Machine. This is run by installing it as Virtual Machine with the VirtualBox program.


* VirtualBox is installed on your PC. To find it open a terminal and
* Yambo Virtual Machine
>which virtualbox
* Yambo Container
/usr/bin/virtualbox
* Install the Yambo source in your computer
* The Yambo Quantum Machine image (.ova file) is already in the /scratch
>cd /scratch
>/scratch$ ls
(...) '''YAMBO_Quantum_Mobile.ova'''

The tutorials can be run on a dedicated Virtual Machine (called '''Yambo Quantum Mobile''' and adapted from the [https://quantum-mobile.readthedocs.io/en/latest/ Quantum Mobile] VM).
* [[Yambo_Virtual_Machine#Starting_the_Virtual_Machine|Start the Yambo Quantum Machine]]
This is run by installing it as Virtual Machine with the VirtualBox program.
To install the Yambo VM in your computer you need to:
* Download and install Virtualbox software
* Download the Yambo Virtual Machine image
* Install the Yambo Virtual Machine
* Start the Yambo Virtual Machine
* Update and install the Tutorials
