 ## DeepCell Spots Application
 
-`deepcell-spots` contains an application that greatly simplifies the implementation of deep learning models for spot detection. `deepcell-spots.applications` contains a pre-trained model for fluorescent spot detection on images derived from assays such as RNA FISH and in-situ sequencing. This model returns a list of coordinate locations for fluorescent spots detected in the input image.
