 # Instant OpenHIE
 
+Welcome to Instant OpenHIE. Open Health Information Exchange (OpenHIE) is a global, mission-driven community of practice dedicated to improving the health of the underserved through open and collaborative development and support of country driven, large scale health information sharing architectures. 
+
+The central technical output of OpenHIE is the consensus-driven OpenHIE Architecture, an open framework to develop health information exchanges (HIEs) to improve patient care, public health, and the management of health resources. The architecture is based upon real-world implementations and needs.
+
+Instant OpenHIE is meant to help implementers to test and try OpenHIE Architecture components and workflows. The goals of Instant OpenHIE are to support:
+* **Demonstrations**: A simple way to launch containers with OpenHIE components and demonstrate workflows.
+* **Simplify life for developers**: A way for implementers to rapidly develop their tooling around the OpenHIE Architecture and the versions of it without having to unnecessary time configuring many components.
+* **QA**: Run workflows in a CI/CD system like GitHub Actions.
+
+Instant OpenHIE is not meant for production and is not a substitute for enterprise-level IT configuration. Implementers should consult the product owners' documentation for production set-up.
