 ### `hot-rebuild`
 
-Adds the `EntryPointExport` resource, which can be used to retrieve an `ExportHandle` corresponding to a JSON output file.
-When passed to a `RustGpu` material, active entrypoints to be aggregated and exported to the corresponding file on change.
+Enables hot-rebuilding support.

+`RustGpu` gains a new `export_to` function, which will register it to export entry points to the provided path.
 
 This can be used in concert with the `hot-reload` feature, [`rust-gpu-builder`](https://github.com/Bevy-Rust-GPU/rust-gpu-builder)'s file watching functionality,

 * The bevy app loads a `RustGpu` material, tries to specialize it, and exports the set of required entry points to `entry_points.json`
 * [`rust-gpu-builder`](https://github.com/Bevy-Rust-GPU/rust-gpu-builder) picks up the change to `entry_points.json` and triggers a recompile
