# Notification templates reference
|
||
|
|
|
||
|
|
In order to customize title and body of notifications you'll have to write a [go template](https://pkg.go.dev/text/template) and mount it inside the `/etc/dockervolumebackup/notifications.d/` directory.
|
||
|
|
|
||
|
|
Configuration, data about the backup run and helper functions will be passed to this template, this page documents them fully.
|
||
|
