+- [**Components**](./components) — containing the React components Slate renders.
+- [**Models**](./models) — containing the models that store Slate's data.
+- [**Plugins**](./plugins) — containing the plugins that ship with Slate by default.
+- [**Serializers**](./serializers) — containing the serializers that ship with Slate by default.
+- [**Utils**](./utils) — containing a few convenience utility modules.
+
+Feel free to poke around each of them for more information!
