+## FHIR
+
+This package also serves as a preview of Dokotela's [FHIR package][fhir_package], which is currently a work in progress. FHIR stands for "Fast Healthcare Interoperability Resources", which is managed by [HL7 International][fhir_info].
+
+In this demo, we connected Dokotela's FHIR package to both [Aidbox][aidbox] and to [HAPI FHIR][hapi_fhir], which have free options to create a FHIR server. This demo includes basic examples on querying vital signs and, creating new patients, and searching for patients.
+
+Please feel free to fork this project and Dokotela's [FHIR package][fhir_package]. You are welcome to suggest changes and submit a pull request to optimize this project. Once the FHIR package complete, we plan to submit this package to [pub.dev][pub] so that all may use.
