What do I need to use it ?

Just a tiny bit of WILLPOWER. 

MARXOSO only needs a desktop or laptop PC, plus a printer if you need reports or race numbers and diplomas.

After downloading the software, have a good look at the Manual and the requirements mentioned: from then on, you can look at the different Tutorials to show you how it all works and how to get the most out of your MARXOSO.

Enjoy it.
