+The preferred way to load a model in Moose is via a JSON file.
+To load an JSON file, all you have to do is to press the _``Import from JSON''_ button in the Moose Panel and indicate the file to load.
 This creates a model, populates it with the entities from the file and adds the model to the repository.
 Visually, the model appears in the list of models from the Moose Panel.
