 ## Quick Introduction
 
-The Smart Device Template (SDT) is a template which is used to model the capabilities, actions and events of connected devices. The intent of the SDT is to be able to model any type of connected device using a well accepted and standardised format. The main application of SDT is to enable a uniformly structured Application Programmer's Interface (API) to applications that need to interact with connected devices. Usually, these applications would communicate to devices using an Abstraction Layer as an intermediary logic. The Abstraction Layer "hides" the technology-specific, native language format of devices of different technology type from the applications.
