1. Install the mod. A readme.txt file is present for the lines of code, and how to install.
For FiveM players, you need to use the dpemotes mod.
For SP players, you can use several different mods to use the animations, including Menyoo which is quite popular, or custom-animations. You install the mod, and drag the files into the folder. A detailed tutorial is on my discord server in how-to-install.
In the case of an installation for SP, you take the lines of code from the README.txt and you insert them afterwards in FavouriteAnims.xml which is located in the menyooStuff folder
