+## Limitations
 
 `vizarr` was built to support the registration use case above where multiple, pyramidal OME-Zarr images
 are viewed within a Jupyter Notebook. Support for other Zarr arrays is supported but not as well tested. 
 More information regarding the viewing of generic Zarr arrays can be found in the example notebooks.
