# Code generation

Code generation is where your modeling work pays off. To trigger it, simply run:

```bash
npx zenstack generate
```

You should see an output similar to:

A full reference of the `zenstack` CLI can be found [here](cli-references.md), but for now knowing just this one command is good enough.

As you see, several code generators are run to create pieces of code that help you build the app. Let's see how to use it in the [next section](building-your-app.md).
