+##### Regular warning
+
+If notifications settings are not set up correctly, there will be a warning in the conversation list. This is displayed regularly unless it is changed in the settings so that you are not reminded of incorrect settings.
+If you select "Not now", the warning will be shown again after a few days if the settings are still wrong. When 
+selecting "Settings", the settings screen will appear. All incorrect settings will blink and their description is in 
+red color. 
+
+##### Notification settings
+
+The notification settings can either be reached when selecting "Settings" in the regular notification warning or by 
+clicking on the user avatar in the right corner of the conversation list and by selecting "Settings".

+Please take into account that the android settings might look different for each manufacturer. 
+You can also reach these settings by long pressing on the Nextcloud Android Talk App in Android itself and by selecting 
+"App info".

       needs.
