Wondering how I actually get this to work in fivem

Hello! I’ve recently been looking around for a decent looking SASP livery for police vehicles for a fivem server, I found this one (link below) but when I downloaded it all that’s in the file is a mixture of png files and dds files. What I’m wondering is, how exactly do I add this to my fivem resources and get it to work on my server, can anyone help?

Just like you would install any other textures/skins. Using something like OpenIV, open the vehicle models, and replace the textures you want with the ones you downloaded. For model specific support, either ask the skin creator or the model creator for help.
