+![Configuring two asset collections](bevy_asset_loader.png)
+
+`bevy_asset_loader` by [@nikl_me] is a plugin for [Bevy][bevy] apps aiming to
+improve a common pattern for asset-loading. The boilerplate required to load
+assets during a "loading state" is reduced to a minimum. At the same time, the
+plugin brings together the internal names of assets and their filepath, making
+it easier to add new assets and to keep an overview over already existing ones.
+
+The library introduces the `AssetCollection` trait that can be derived. Any
+number of asset collections can be loaded by a single `AssetLoader` during a
+configured app state. When all assets are loaded, the collections will be
+inserted into Bevy's ECS as resources. Afterwards, the `AssetLoader` will
+switch into a second configurable app state. At this point, your app can use
+the asset collections that now contain loaded asset handles.
+
+Currently, a single file always corresponds to one asset and more complex
+assets like e.g. `TextureAtlas` are not yet supported. There are plans to
+extend the `asset` attribute to allow loading more complex assets. Stay tuned!
