+# Vectorize RAG in Python
+
+This example shows how to build a very simple Vectorized document retrieval system using Cloudflare's Vectorize service and Python workers.
+
+> **Note:** This example uses remote Workers AI and Vectorize resources, which are billable, even in local development.
+
+## Local development
+
+```bash
+npx wrangler login
+# Select the intended account if Wrangler prompts for one.
+npx wrangler vectorize create python-rag-index --dimensions=768 --metric=cosine
+uv run pywrangler dev
+```
+
+### Seeding
+
+```bash
+curl -X POST http://localhost:8787/seed
+```
+
+Seed the four-document to the Vectorize index.
+
+### Querying
+
+```bash
+curl -X POST http://localhost:8787/query \
+  -H 'content-type: application/json' \
+  --data '{"question":"What does Vectorize store?"}'
+```
+
+## Endpoints
+
+- `GET /` describes the setup and models.
+- `POST /seed` embeds and upserts the documents.
+- `POST /query` accepts `{"question":"..."}` and returns a grounded `answer` plus match IDs, titles, scores, and citations.
