+Each Dandiset is represented as a separate DataLad dataset.
+<https://github.com/dandi/dandisets/> is a [DataLad superdataset](https://handbook.datalad.org/en/latest/glossary.html#term-DataLad-superdataset) that includes all individual Dandiset datasets as subdatasets ([git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules)).
 Where present, individual [Zarr](https://zarr.dev/) files are included as subdatasets ([git submodules](https://git-scm.com/book/en/v2/Git-Tools-Submodules)) hosted in the GitHub organization <https://github.com/dandizarrs/>.

 - clone an entire dataset,
 - use a specific version of it,
