 To use this project, you need to have a `.csv` file with the knowledge base and a `.toml` file with your prompt configuration.
 
 We recommend that you create a folder inside this project called `data` and put CSVs and TOMLs files over there.

+## Generate an embedding `load_csv.py`
+
+Embeddings create a vector representation of a question and answer pair from the knowledge base, enabling semantic search where we look for text passages that are most similar in the vector space.
+
+We have a CLI that generates embeddings by reading the knowledge base `csv`.
+By default, `load_csv.py` performs a **diff** between the existing vector database and the new questions and answers in the `csv`.
+
+The **CLI** has some parameters:
+
+*`--path`: path to the CSV (knowledge base)
+*`--cleandb`: deletes all previously imported vectors and reimports everything again.
