Putting it all together here is an example configuration file.

```ini
[[config]]
template = "/etc/nginx/nginx.conf.tmpl"
dest = "/etc/nginx/sites-available/default"
onlyexposed = true
notifycmd = "/etc/init.d/nginx reload"

[[config]]
template = "/etc/logrotate.conf.tmpl"
dest = "/etc/logrotate.d/docker"
watch = true

[[config]]
template = "/etc/docker-gen/templates/nginx.tmpl"
dest = "/etc/nginx/conf.d/default.conf"
watch = true
wait = "500ms:2s"

[config.NotifyContainers]
nginx = 1  # 1 is a signal number to be sent; here SIGHUP
e75a60548dc9 = 1  # a key can be either container name (nginx) or ID
```
