 ## Visualise an atlas in napari
 
-BrainGlobe atlases are made of different components. These include the annotations image, the (default) reference image, 3D brain region meshes and, optionally, additional reference images. In this tutorial, you will use `brainrender-napari` to visualise each of these components in the 3D viewer napari through a series of simple clicks. The [`mpin_zfish_1um` zebrafish brain atlas](https://doi.org/10.1016/j.neuron.2019.04.034) will serve as an example.

 If you haven't downloaded the atlas before, the plugin will prompt you to download it (click yes). It may take a long time
-(depending on your internet speed) so please be patient. Once downloaded, double click again to view the atlas.

-You have now added all possible kinds of BrainGlobe atlas components (annotations image, reference image, 3D brain region mesh, additional reference) to napari - well done! You can now add any of the other atlases listed in the `Atlas table view` if you like (note that not all atlases have additional references!).
