 ## Using Starling
 
 Starling provides a framework for users to implement almost any drone related experiment or application. However, we have identified that most applications fall into the following categories. Therefore we have provided detailed user guides for these use cases. It is recommended that the user follow these guides to run starling before starting your own implementation as these guides will also slowly introduce you to the concepts and details Starling uses.
