These tutorials teach FIWARE users about how to create and manage context data subscriptions. The tutorials build on the

entities and Stock Management / Smart Farm

applications created in previous tutorials to enable users to fully

understand the NGSI Subscribe/Notify paradigm and how to

use NGSI subscriptions within their own code.

The tutorial refers to actions made within the browser combined with [cUrl](https://ec.haxx.se/)

commands. The cUrl commands are also available as

[Postman documentation](https://www.postman.com/downloads/)
