 ## Using `brainglobe-heatmap` with other atlases.
 
-`brainglobe-heatmap` uses `brainrender` which, in turn, uses brainglobe's `Atlas API` under the hood. That means that all of `brainglobe-heatmap`'s functionality is compatible with any of the atlases supported by the atlas API. `bgh.heatmap`, `bgh.planner` and `bgh.get_plane_coordinates` all accept a `atlas_name` argument, pass the name of the atlas name you'd like to use!
