1. **A user asks a question** - The bot responds in the channel
2. **Review the response** - If the answer needs improvement, reply in the thread to the bot's message
3. **Provide corrections** - Add missing context, correct inaccuracies, or clarify the response
4. **Request indexing** - Ask the bot to index the improved response (e.g., "Index this response" or "Please save this")
5. **Iterate if needed** - The bot will generate an improved answer. Continue refining until you're satisfied
6. **Confirm indexing** - When the response looks good, tell the bot to save it. The bot will confirm the Q&A pair has been indexed
2. **Review the response** - If the answer needs improvement, reply in the thread to the bot's message

Once indexed, Ask Fern will use this curated question-answer pair to inform future responses to similar questions, giving more accurate answers over time.

## Architecture

When a user asks Ask Fern a question in Slack, a webhook triggers Fern's servers to search your documentation database and retrieve relevant context. Using that context, Ask Fern generates a response.
