There are two components: ingestion and question-answering.

Ingestion has the following steps:

1. Pull html from documentation site
2. Parse html with BeautifulSoup
3. Split documents with LangChain's TextSplitter
4. Create a vectorstore of embeddings, using LangChain's vectorstore wrapper (with OpenAI's embeddings and Weaviate's vectorstore)

Question-Answering has the following steps:

1. Given the chat history and new user input, determine what a standalone question would be (using GPT-3)
2. Given that standalone question, look up relevant documents from the vectorstore
3. Pass the standalone question and relevant documents to GPT-3 to generate a final answer

Coming soon.
