+## YunoHost specific features
 
-## About telemetrics
+#### Multi-user support
 
-Mattermost can collect some anonymous telemetrics about your usage of the software. These data are sent to a third-party service named [segment.com](https://segment.com/).
-You can find more information about this behavior in the [Mattermost documentation](https://docs.mattermost.com/administration/telemetry.html).
+ * Are LDAP and HTTP auth supported?
+ * Can the app be used by multiple users?
 
-In this Yunohost package telemetrics collection is strictly opt-in, and can be turned on or off before the app is installed.
+#### Supported architectures
