-# Publish Dandisets with Zarr archives
+# Support updates to Zarr archives after publishing the corresponding Dandiset
 
 This document describes the current implementation of publishing Dandisets with Zarr archives, a desired use case, and the associated requirements of this use case.
 
 ## Current implementation
 
-Currently when a blob asset is updated, a new version (i.e. a copy) is uploaded to S3.  Zarr archives are too large so multiple copies should not be created.  A Zarr archive is uploaded once and it is edited in place.  This design means that the Zarr archive is immutable once the Dandiset is published.  For more details, see the [zarr-support-3 design doc](https://github.com/dandi/dandi-archive/blob/master/doc/design/zarr-support-3.md).

 ## Use case 1
 
-Publish Dandisets with Zarr archive(s) following the general publishing procedure described in the [publish-1 design doc](https://github.com/dandi/dandi-archive/blob/master/doc/design/publish-1.md).  A modified publishing procedure that includes Zarr archive(s) is summarized below.
+Publish a Dandiset containing a Zarr archive(s), and subsequently update the Zarr archive(s).
 
-1. User uploads a new Dandiset which includes Zarr archive(s).
-2. User uploads an updated Zarr archive in the `Draft` version of the Dandiset.  
-3. User publishes the Dandiset and thereby creates a new version of the Dandiset.
+The publishing procedure would follow the description found in the [publish-1 design doc](https://github.com/dandi/dandi-archive/blob/master/doc/design/publish-1.md).  A modified publishing procedure that includes Zarr archive(s) is summarized below.
+
+1. User uploads a new Dandiset which includes a Zarr archive(s).
+2. User uploads an updated Zarr archive(s) to the `Draft` version of the Dandiset.  
+3. User publishes the Dandiset and thereby creates a new immutable version of the Dandiset.
 4. User repeats steps 2 and 3.
 
 ## MVP Requirements (Target date: April 30, 2024)
 
-1. Permit versioning of Zarr archives without creating a copy of the entire Zarr archive
-1. Permit publishing of Dandisets with Zarr archives
-1. Minimize storage costs in the design
+1. Support versioning of Zarr archives without creating a copy of the entire Zarr archive.
+1. Support publishing immutable versions of Dandisets with Zarr archives, where the Zarr archives are potentially updated between versions.
+1. Minimize storage costs in the design.
 
 ## MVP+1 Requirements
 
-1. Permit linking of a Zarr asset to multiple Dandisets - [dandi-archive/issues/1792](https://github.com/dandi/dandi-archive/issues/1792)
