pls help

For maps:

• First thing to do is to slide your modded map’s zip file in your server’s (Ressources/Client) folder.
• Next, open the map’s zip file and open the (levels) folder. You should now see your map’s main directory. For my example it’s named bajarama.
  So, it should be ((yourmoddedmap)\levels\(mapname)). Copy the (mapname) part.
• Then, add it to the regular map path and it gives you this (/levels/(mapname)/info.json). With my example, it will be (/levels/bajarama/info.json).
• Copy that directory and paste it in your server config file’s map selection part.

Vehicle mods and map mods are different to install, but both require you to put them in your server’s (Ressources\Client) folder. Simply slide any mod you want to add in that folder. (Leave it as a zip!

You need to arrange the files correctly

but there is no /levels/ repository, so how to add it in there?
