+# DocsGPT
+
+[DocsGPT](https://docsgpt.arc53.com/) is an open-source documentation assistant that enables you to build conversational user experiences on top of your data.
+
+Qdrant is supported as a vectorstore in DocsGPT to ingest and semantically retrieve documents.
+
+## Configuration
+
+Learn how to setup DocsGPT in their [Quickstart guide](https://docs.docsgpt.co.uk/Deploying/Quickstart).
+
+You can configure DocsGPT with environment variables in a `.env` file.
+
+To configure DocsGPT to use Qdrant as the vector store, set `VECTOR_STORE` to `"qdrant"`.
+
+```bash
+echo "VECTOR_STORE=qdrant" >> .env
+```
+
+DocsGPT includes a list of the Qdrant configuration options that you can set as environment variables [here](https://github.com/arc53/DocsGPT/blob/00dfb07b15602319bddb95089e3dab05fac56240/application/core/settings.py#L46-L59).
