There are two documentation patches now, submitted to LangChain as drafts. They will need to receive more love, so they are looking for volunteers. Storytelling skills are beneficial.

• community: CrateDB: Documentation about Vector Store, Document Loader, and Conversational Memory langchain-ai/langchain#27713
• docs: Add how-to guide for SQLDatabaseLoader langchain-ai/langchain#27696
