+# Prescribing Information App
+
+This is a Python application built with [Writer Framework](https://github.com/writer/writer-framework) that provides detailed prescribing information, side effects, and related PubMed articles for medications. The app uses the OpenFDA API and PubMed database to gather comprehensive drug information and present it in an easily digestible format. This application uses [Palmyra Med](https://huggingface.co/Writer/Palmyra-Med-70B) to summarize the prescribing information and our [graph-based RAG tool](https://dev.writer.com/api-guides/kg-chat) powered by Palmyra X 004 to enable users to ask questions about the fetched information.
+
+To learn more about Writer Framework, check out our [comprehensive docs](https://dev.writer.com/framework/introduction).
