Hi there, the installation is simple:

1. Go to your Grand Theft Auto V folder:
  - Steam: "C:\Program Files (x86)\Steam\steamapps\common\Grand Theft Auto V"
  - Rockstar Games: "C:\Rockstar Games\Grand Theft Auto V"
  - Epic Games: "C:\Program Files (x86)\Epic Games\Grand Theft Auto V"

2. Copy everything in the 'Files' from this current folder.
3. Paste those files into your 'Grand Theft Auto V' folder
4. Don't forget to load the plugin.

- If you want to change the settings, go into "plugins\Seatbelt.ini"
- In-game settings menu: F4 > "OpenSeatbeltSettings"
- Use Left Control or DPad Up to interact.

TIP: If you right-click the Grand Theft Auto V folder and 'Pin to Quick Access' you can get there more easily in the future.
 
 
Want to load the plugin automatically?
When you start LSDPFR, immediately press on the ⚙️ icon, go to the 'Plugins' tab, and then make sure "Seatbelt" is checked, then on the bottom-right you will see "Save and launch", press that and it is good to go.
