Resources can be used to add functionality to your server. You can find many of the available resources on the Cfx Marketplace or in the FiveM Releases / RedM Releases section.
Some may be free, and others may not be. The forum and the Cfx Marketplace have filtering functionality, so you can sort through them.

Use resources at your own risk. Resources are community-driven, and you should choose them carefully. Cfx is not responsible for any issues resulting from their use and will not provide support for community-made resources. Make sure to follow each resource's terms and conditions. Resources generally provide a way to contact the creator for support. Use the available channels if an issue arises.
