RSS Feed allows you to subscribe to news, especially news sites. You need the URL of the RSS Feed for the application, such as http://servis.idnes.cz/rss.aspx?c=zpravodaj.
You then select the maximum number of characters per rss message - the fewer characters, the more space to display more messages. Set the number of seconds to read one message and check your chosen feed layout. If required, the RSS Feed Provider logo can also be uploaded.
