+## Introduction
+SLA4OAI is an open source standard for describing SLA in APIs.
+
+Based on the standards proposed by the [OAI](https://openapis.org/specification), SLA4OAI builds on top of it to add an optional profile
+for the definition of SLA (Service Level Agreements) on the APIs.
+
+This SLA definition in a neutral vendor flavour will allow to foster innovation in the area where APIs expose and documents its SLA, 
+API Management tools can import and measure such key metrics and composed SLAs for composed services aggregated way in a standard way.
