Where should I begin?

Hello,

I'm am spanking brand new to the Fortigate world!!!  The only thing that I'm absolutely certain of, that relates to Fortigate, is how to spell it!!!

My question is, what Fortiget training should I begin with?  I'm not new to networking, nor am I new to cybersecurity, but I'm a newborn in the world of Fortinet!!!  

Many thanks in advance!!!
