#### Docker for development

Alternatively you can use Docker for the development setup. This requires Docker
and Docker Compose installed.

```
make build
make bundle
```

And in order to run the tests and linter checks:

```
make test
```

After you're done, cleanup leftover containers:

```
make cleanup
```
