+## Development Builds
+
+If you want to try out the latest changes without waiting for a stable release, you can use the development builds. These builds include new features, bug fixes, and improvements but may also be unstable.
+
+!!! warning "Try at your own risk!"
+    These builds allow you to experience new changes before they are officially released. These builds are not thoroughly tested, so the chance you may experience crashes, bugs, or other issues is higher than with stable versions. If you encounter problems, consider reporting them on the [Rigs of Rods GitHub issues](https://github.com/RigsOfRods/rigs-of-rods/issues) page.
