+# napari-boxmanager
+
+The napari module is built in combination with the crYOLO module : 
+
+From crYOLO/1.9.9 crYOLO exists as two different conda envs, one crYOLO (code itself) env, one napari (visualization) env. 
+The installation notes recommend to link one into another, on Merlin7 simply two different modules and envs exist.
+Users need to load one env in one terminal ( crYOLO itself) and another for visualization (napari).
+
+## Adding New Versions
+
+Adding new versions: change the environment file in the build folder accordingly (and the config.yaml file)  and run the build script.
