+# Page Title service
+
+Sets the page title.
+
+## Methods
+
+-   `setTitle(value: string = '')`  
+    Sets the page title.  
+    -   `value` - The new title
+
+## Details
+
+If an application name is supplied in the app config file then this will
+be concatenated with the `value` parameter when `setTitle` is called, giving
+a result of the form "PageName - AppName" (see
+[App Config service](app-config.service.md) for more information). If `value`
+is not supplied then just the app name is used; this will default to
+"Alfresco ADF Application" when no app name set in the config file.
