+In BepInEx, we no longer use a `mod.json` file to determine dependencies. Instead, this is done via the `[BepInDependency]` attribute.
+You can mark Nautilus as a dependency to your mod by simply adding the `[BepInDependency("com.snmodding.nautilus")]` attribute at the top of your entry point class. [Example](https://github.com/SubnauticaModding/Nautilus/blob/master/Example%20mod/CustomPrefabExamples.cs#L11)
