-# AddressablesStorage
+# BrainAtlas
 
-The AddressablesStorage package hosts remote builds of various asset files that are shared across Virtual Brain Lab projects. These files can be accessed by using the functions in the [AddressablesRemoteLoader](https://github.com/dbirman/vbl-core/blob/main/Scripts/Addressables/AddressablesRemoteLoader.cs) class found in the vbl-core repository. 
+This repository is a wrapper around the [BrainGlobe Atlas API](https://github.com/brainglobe/bg-atlasapi). The pipeline files download the atlases from BrainGlobe and re-package them as Asset Bundles. The Addressables in the Unity project can then be built and deployed on a remote server for use by other projects.
+
+The [AddressablesRemoteLoader](https://github.com/dbirman/vbl-core/blob/main/Scripts/Addressables/AddressablesRemoteLoader.cs) class found in the vbl-core repository provides access in client code to the Addressables bundles. (todo: re-name "BrainAtlasLoader")
