 This template demonstrates the multi-vector indexing strategy proposed by Chen, et. al.'s [Dense X Retrieval: What Retrieval Granularity Should We Use?](https://arxiv.org/abs/2312.06648). The prompt, which you can [try out on the hub](https://smith.langchain.com/hub/wfh/proposal-indexing), directs an LLM to generate de-contextualized "propositions" which can be vectorized to increase the retrieval accuracy. You can see the full definition in `proposal_chain.py`.

 To create a new LangChain project and install this as the only package, you can do:
 
 ```shell
-langchain app new my-app --package rag-chroma-dense-retrieval
+langchain app new my-app --package propositional-retrieval
 ```
 
 If you want to add this to an existing project, you can just run:
 
 ```shell
-langchain app add rag-chroma-dense-retrieval
+langchain app add propositional-retrieval
 ```
 
 And add the following code to your `server.py` file:
 
 ```python
-from rag_chroma_dense_retrieval import chain
+from propositional_retrieval import chain
 
-add_routes(app, chain, path="/rag-chroma-dense-retrieval")
+add_routes(app, chain, path="/propositional-retrieval")
 ```
 
 (Optional) Let's now configure LangSmith.
