# Install the webhook with Helm
Install the webhook with Helm. Pass in your `custom.yaml` configuration file created in the previous step with the `--values` flag.
```bash
helm install [name] \ 
  elastic/apm-attacher \
  --namespace=elastic-apm \ 
  --create-namespace \
  --values custom.yaml
```

<note>
  `helm upgrade ...` can be used to upgrade an existing installation, eg if you have a new version of the `custom.yaml` configuration file.
