Open Telegram and message @BotFather\n2. Use `/newbot` to create your bot and note the token\n3. In n8n, go to Credentials → Add Credential → Search \"Telegram API\"\n4. Paste the token and save\n\n### Google Gemini API Setup\n1. Visit aistudio.google.com and sign in with Google\n2. Click \"Get API key\" → Create API key in a new project\n3. In n8n, go to Credentials → Add Credential → Search \"Google Gemini API\"\n4. Enter the API key and save\n\n## ⚙️ Configuration Steps\n1. Import the provided JSON into your n8n workflows\n2. Assign the Telegram credential to the trigger and Telegram nodes\n3. Assign the Gemini credential to the Edit Image node\n4. Activate the workflow and note your bot's username\n5. Test by sending an image document with a caption to your bot\n\n## 🎯 Use Cases\n- **Personal creativity**: Send a selfie with \"make me a superhero\"\n- **Social media**: Upload photos with \"enhance lighting\"\n- **Educational**: Share sketches with \"colorize and detail\"\n- **Team collab**: Prompt \"remove background\" in groups\n\n## ⚠️ Troubleshooting\n- **No trigger**: Verify token and enable message updates\n- **Download fail**: Resend file; check it's a document\n- **Edit error**: Check API quotas; shorten prompts\n- **No send**: Verify binary data in execution log"
