 // TODO: automatic cache eviction
 
+/// Install the default set of loaders:
+/// - `file` loader on non-Wasm targets
+/// - `http` loader with the `ehttp` feature
+/// - `image` loader with the `image` feature
+///   - the supported set of image formats is configured by enabling `image` crate features.
+/// - `svg` loader with the `svg` feature
+///
+/// The `file` and `http` loaders are bytes loaders, they do not know how to turn those
+/// bytes into an image. `svg` is for loading `.svg` files, and `image` can load any
+/// other image format enabled on the `image` crate.
