An LLM turns the article into slide copy, which is parsed and split into individual slides.\n3. For each slide a background image is generated with an AI model, downloaded, and uploaded to Posta.\n4. The slides are re-assembled and rendered into a text carousel PDF.\n5. Posta publishes the carousel to your connected LinkedIn account.\n\n### Setup steps\n\n- [ ] Add your Posta credential (API token) to the Posta nodes\n- [ ] Add your DeepSeek (LLM) credential to the 'Basic LLM Chain' model\n- [ ] Add your fal.ai credential for AI background generation\n- [ ] Set the RSS feed URL and pick the LinkedIn account in 'Get many social accounts'\n\n### Customization\n\nAdjust the number of slides and the 'theme_color' to match your brand styling."
