-## The `getDescription` function
-
-This function returns the description of a bridge.
-
-**Notice:** **RSS-Bridge** will by default return `const DESCRIPTION` which is defined in the bridge, so you only have to implement this function if you require different behavior!
-
-```PHP
-	public function getDescription(){
-		return self::DESCRIPTION;
-	}
-```
-
 ## The `getMaintainer` function
 
 This function returns the maintainer name of a bridge.
