+### Filesystems
+
+Lodata supports read, update, create, delete and query options on Laravel filesystems.
+
+The `FilesystemEntityType` provides an entity type starting point, with the key property set to a `String` key named
+`path`. The `FilesystemEntitySet` can then be attached to expose the filesystem. The entity set supports a `setDisk`
+method to set the filesystem to use.
+
+```
+$entitySet = new FilesystemEntitySet('files', new FilesystemEntityType());
+$entitySet->setDisk('default');
+Lodata::add($entitySet);
+```
+
+The filesystem entity type supports a `Edm.Stream` property named `content` that can be requested with `$select` which
+will encode the file into the body of the response. The URL to retrieve the file will also be provided in the body as
+the metadata `content@mediaReadLink`.

 ### Annotations
 
 OData allows the creation of annotations on the schema. Annotations are classes that extend `\Flat3\Lodata\Annotation`
-and are added to the model with `Lodata::add($annotation)`, or entity set types with `EntitySet::addAnnotation($annotation).
+and are added to the model with `Lodata::add($annotation)`, or entity set types with `EntitySet::addAnnotation($annotation)`,
+or entity type properties with `Property::addAnnotation($annotation)`.
 Examples are in the `\Flat3\Lodata\Annotation` namespace.
