 ### Transform Plugins
 Transform plugins (or filter plugins?) can interject in three places:
-* Transform a `VfsItem` that's being read into an `RbxItem` in the VFS
+* Transform a `VfsItem` that's being read into an `RbxInstance` in the VFS
 * Transform an `Rbxitem` that's being written into a `VfsItem` in the VFS
 * Transform a file change into paths that need to be updated in the VFS watcher
