 ## UUID and Secret
 
-To authenticate with the openHAB Cloud service the add-on generates two values when the add-on is installed.
+To authenticate with the openHAB Cloud service, the add-on generates two values when the add-on is installed.
 These values need to be entered in your account settings of the openHAB Cloud service.
+
 The first one is a unique identifier, which allows to identify your runtime.
 One can think of it as something similar like a username for the cloud authentication.
 The second one is a random secret key which serves as a password.
 Both values are written to the local file system.
+
 If you loose these files for some reason, openHAB will automatically generate new ones.
 You will then have to reconfigure UUID and secret in the openHAB Cloud service under the _My account_ section.
 You will need these values to register on the website before connection is accepted.
 
 Location of UUID and Secret:
