Second Method

The second method is also very similar to the first one.

To begin, go to FiveM website and look for the Mods you like to try. When you have found the Mods you're looking for, download the files. These are usually downloaded in zip files.

After downloading the Mods, open the FiveM directory and look for resources folder and open it. To keep things organized, it is best to add a new folder (this will allow you to get rid of the file easily if something goes wrong, or you don't like the Mod).

Rename the new folder that you just created. You can name whatever you want, but make sure that the name you use is easy to remember, and use a bracket. For example, the file name must look similar to this [Tommy] Adding a bracket to the folder name eliminates the need to move the files into the resources folder.

Now, move the downloaded files into the new folder you just created. All the files that you move into this folder should be edited. You don't have to rename the contents, just use the default name, but the file names should begin with a start and space. You can do this with the help of Notepad ++. The edited file should look something like this; start FileName.

That's it. The Mods should be in the game already. Restart your server and see if the Mod menu is working.
