Connect your **RSS Feed** node and set the Stack Overflow tag query.  \n2. Add **OpenAI credentials** (model: gpt-4o-mini).  \n3. Connect your **Notion** workspace and choose your FAQ database.  \n4. Link your **Google Sheets** account and specify the document + sheet.  \n5. Connect **Slack**, select your workspace, and set a target channel ID.  \n6. Run once manually to test and confirm that all nodes are working.\n"
