Now let's take a look at what has been generated. Let's open the application code in our favorite IDE/editor and look at what has been generated for the Product entity.

You might have noticed that there is a .jhipster folder at the root of the project, and if you look inside it, you will see a bunch of JSON files. Let's look at Product.json; it holds metadata about the generated entity and is used by JHipster to regenerate and edit an entity when needed:
