### Requirements
| Requirement | Version | Install |

| **n8n** | 1.0+ | [Self-hosted install guide](https://docs.n8n.io/hosting/) |
| **Ollama** | 0.1.0+ | [ollama.com/download](https://ollama.com/download) |
| **Model** | llama3.1:8b | `ollama pull llama3.1:8b` |

curl -fsSL https://ollama.com/install.sh | sh
# 2. Pull the model
ollama pull llama3.1:8b
# 3. Verify Ollama is running
curl http://localhost:11434/api/tags
```
### Import a workflow
1. Open n8n (`http://localhost:5678`)
2. **Workflows** → **Add Workflow** → **Import from File**
3. Select any `.json` file from the `workflows/` folder
4. Click **Activate** (toggle in top-right)

## Customization
- **Change the model:** Edit the `model` field in Ollama HTTP Request nodes. Try `mistral`, `phi3`, `gemma2`, or anything from the [Ollama library](https://ollama.com/library).
- **Adjust creativity:** Lower `temperature` (0.1) for factual tasks, higher (0.7+) for creative output.
- **Increase output length:** Raise `num_predict` for longer responses.
- **Add authentication:** Enable header auth on Webhook nodes for production use.
---
## Troubleshooting
| Issue | Solution |
|---|---|
| "Connection refused" on Ollama calls | Make sure Ollama is running: `ollama serve` |
| Slow responses | Try a smaller model: `phi3:mini` or `gemma2:2b` |
| "Model not found" | Pull the model first: `ollama pull llama3.1:8b` |
| Webhook not responding | Ensure the workflow is **activated** in n8n |
| Timeout errors | Increase timeout in the HTTP Request node options |
