Where does 'db' comes from?

[enbits]

Hey, thanks for this amazing boilerplate. This is not an issue but more like a question:

In Project.js file you import a 'db' module, but I can't find it anywhere, where does it comes from?

You've probably figured it out by now but db comes from /storage/index.js, which exports Sequelize(uri)
