+### Warning on configuration of Notifier component
+
+If installed in an symfony app where the recipes are activated, this configuration should be added automatically:
+
+```yaml
+framework:
+    notifier:
+        chatter_transports:
+        texter_transports:
+            ovhcloud: '%env(OVHCLOUD_DSN)%'
+        channel_policy:
+            # use chat/slack, chat/telegram, sms/twilio or sms/nexmo
+            urgent: ['email']
+            high: ['email']
+            medium: ['email']
+            low: ['email']
+        admin_recipients:
+            - { email: admin@example.com }
+```
+
+Actually, you should either:
+
+- remove the configuration of ovhcloud added by the recipe
+- or remove the previous configuration of chill, to avoid keeping legacy configuration
+
+#### Remove the added configuration and keep the legacy configuration
+
+To remove the configuration:
+
+```diff
+framework:
+    notifier:
+        chatter_transports:
+        texter_transports:
+-            ovhcloud: '%env(OVHCLOUD_DSN)%'
+```
+
+In that case, the previous configuration, which was stored under the `chill_main.short_messages.dsn` will be reconfigured into the Notifier component's configuration.
+
+#### Properly configure SMS
+
+You can also properly configure it, as [described in the OVH cloud provider repository](https://github.com/symfony/ovh-cloud-notifier/tree/5.4?tab=readme-ov-file#dsn-example) (where the scheme is `ovhcloud`):
+
+**NOTE**: You have access to all notifier available with the [Notifier component](https://symfony.com/doc/current/notifier.html#notifier-sms-channel). You are not restricted to use OVH as a provider.
+
+```diff
+framework:
+    notifier:
+        chatter_transports:
+        texter_transports:
++            ovhcloud: '%env(OVHCLOUD_DSN)%' # this value should be located in a variable, and have `ovhcloud://` as a scheme
+
+chill_main:
+-    short_messages:
+-        dsn: '%env(string:SHORT_MESSAGE_DSN)%'
+```
