 [![CI Status](https://microsofthealthoss.vsrm.visualstudio.com/_apis/public/Release/badge/7621b231-1a7d-4364-935b-2f72b911c43d/1/1)](https://microsofthealthoss.visualstudio.com/FhirServer/_releases2)
 
-## Deployment
+FHIR Server for Azure is an open source implementation of the emerging HL7 Fast Healthcare Interoperability Resources (FHIR) specification designed for the Microsoft cloud. The FHIR specification defines how clinical health data can be made interoperable across systems, and the FHIR Server for Azure helps enables that interoperability in the cloud. 
+
+The FHIR specification helps enable compliant healthcare data transmission, storage and sharing. This “data liquidity” enables healthcare providers, clinical researchers, payors, biotech labs, and other health and life science organizations to exchange and integrate clinical data in the pursuit of improved outcomes and efficiencies. 
+
+Bringing health data into Azure enables new cloud and AI scenarios and use cases in research, clinical trials, population health management, and other healthcare innovations. Health data liquidity is necessary to unlocking interoperability with the primary system of record — the Electronic Health Record (EHR) — and contributing clinical data that is enriched through analytics and machine learning in the cloud back into the EHR. 
+
+FHIR Server for Azure provides an opportunity to drive interoperability with traditional health data as well as evolving and emerging data types (e.g. big data, IoMT, genomics and immunomics). 
+
+Privacy and security are top priorities and the FHIR Server for Azure has been developed in support of requirements for Protected Health Information (PHI). All the Azure services used in FHIR Server for Azure [meet the compliance requirements for Protected Health Information](https://www.microsoft.com/en-us/trustcenter/compliance/complianceofferings).
+
+This open source project is fully backed by a Microsoft engineering team in the Microsoft Healthcare group, but we know that this project will only get better with your feedback and contributions. We are actively driving the development of this code base and tests builds and deployments daily.
