+# Rig-Qdrant
+
+Vector store index integration for [Qdrant](https://qdrant.tech/). This integration supports dense vector retrieval using Rig's embedding providers. It is also extensible to allow all [hybrid queries](https://qdrant.tech/documentation/concepts/hybrid-queries/) supported by Qdrant.
+
+You can find end-to-end examples [here](https://github.com/0xPlaygrounds/rig/tree/main/rig-qdrant/examples).
