Please follow the Introduction to start developing with us and make parking lots smarter!​ {% hint style="success" %} Check out also the documentation of [**NextPark**](https://docs.nextpark.io/) **- The Sales Network of Parking lots!** {% endhint %} The API is organized according to the REST architectural pattern.
