Is there any design guides or documents for Fortinet Firewall products?

Hi!

May be I asked this before or someone else but I cannot some design guides or documents like other vendor provides on fortigate website. All I can find is small videos by fortinet team. There is big gap in terms of that in camparin with other vendors.

Let say I am trying to find some design scanrio for Fortigate 100E and dont find it.

Hardware switching: I only find few blogs and its definition.

I think Fortigate should come up with more detail about their product and functions.

If there exist please point me to it?

Thanks.
