How to add weapons with ttt weapon placer?

I don’t understand ttt weapon placer and I want to know if there is any other way?

If you are trying to change the weapon spawns on your TTT Server, the easiest way is using the TTT Weapon Placer. I’m pretty sure there are some tutorials on YouTube.

If you want to do it yourself, you’re going to have to edit the weapon spawns manually usually under:
gamemodes/terrortown/content/maps/mapname.txt

It can be pretty complicated editing it manually though, so I recommend finding a tutorial on how to use the TTT Weapon Placer.
