During local development, there is a script that builds the site and checks for any changes, live-reloading:

<div class="termy">

```console
$ python ./scripts/docs.py live

<span style="color: green;">[INFO]</span> Start watching changes
<span style="color: green;">[INFO]</span> Start detecting changes

</div>

Add below section to your `prometheus.yml`
```yaml
alerting:
  alertmanagers:
  - static_configs:
    - targets: ['localhost:9093']
rule_files:
  - rules.yml
