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"
