# 39-flake-apps

This example shows dedicated `apps.<system>` outputs.

It includes:

- one default app that prints a rollout report,
- one named app, `promote`, that prints the next rollout wave,
- package outputs that back those apps, and
- a check that runs both app programs.

Useful commands:

```bash
nix flake show
nix run
nix run .#promote
nix build .#report
nix flake check
```
