+We will build live image search and query it with natural language, using multimodal embedding model. We are going use CocoIndex to build real-time indexing flow. During running, you can add new files to the folder and it only process changed files and will be indexed within a minute.
 
+We appreciate a star ⭐ at [CocoIndex Github](https://github.com/cocoindex-io/cocoindex) if this is helpful.

+## Technologies
+- CocoIndex for ETL and live update
+- CLIP ViT-L/14 - Embeddings Model for images and query
 - Qdrant for Vector Storage
-- CLIP ViT-L/14 - Embeddings Model for both images and text
-- Live Update
-
-## Make sure Postgres and Qdrant are running
-```
-docker run -d -p 6334:6334 -p 6333:6333 qdrant/qdrant
-export COCOINDEX_DATABASE_URL="postgres://cocoindex:cocoindex@localhost/cocoindex"
-```
-
-## Create Qdrant Collection
-```
-curl -X PUT 'http://localhost:6333/collections/image_search' \
-  -H 'Content-Type: application/json' \
-  -d '{
-    "vectors": {
-      "embedding": {
-        "size": 768,
-        "distance": "Cosine"
+- FastApi for backend
