   - ``large-image-source-vips``: A tile source for reading any files handled by libvips.  This also can be used for writing tiled images from numpy arrays.
 
+  - ``large-image-source-zarr``: A tile source using the zarr library that can handle OME-Zarr (OME-NGFF) files as well as some other zarr files.
+
   - ``large-image-source-test``: A tile source that generates test tiles, including a simple fractal pattern.  Useful for testing extreme zoom levels.
 
   - ``large-image-source-dummy``: A tile source that does nothing.
