+
+Next steps / ideas:
+ * Use more caching. For example, load the vector store instead of creating a new one.
+   (try downloading the files created in co-lab session)
+ * Download the files from your notebook and store them in your Chainlit repo so you won't be recreating them every time you run the notebook (which will be a lot faster). 
+ * Get FAISS working on local files [see reference](https://python.langchain.com/v0.1/docs/integrations/vectorstores/faiss/#saving-and-loading)
