Sorry for being such a newb, but I'm just getting into running Delta Green on Fantasy Grounds with this extension. Has anyone done a video on how to setup a campaign using the extension?

Specific questions I have are, does the weapons include lethality in the extension?
When I started a Delta Green Campaign with CoC 6E and the DG Extension, it seems like all of the weapons were still set up for Call of Cthulhu.

There are no professions set up in the extension, so you'd just have to type everything in, right? I noticed some skills like HUMINT and SIGINT aren't in the skills list. Just add those on each character sheet right?

Thanks in advance for any response.
