# Setup Guide
Quick setup instructions for DeerFlow.
## Configuration Setup
DeerFlow uses a YAML configuration file that should be placed in the **project root directory**.
### Steps
1. **Navigate to project root**:
```bash
cd /path/to/deer-flow
```
2. **Copy example configuration**:
```bash
cp config.example.yaml config.yaml
```
3. **Edit configuration**:
```bash
# Option A: Set environment variables (recommended)
export OPENAI_API_KEY="your-key-here"
# Option B: Edit config.yaml directly
vim config.yaml # or your preferred editor
```
4. **Verify configuration**:
```bash
cd backend
python -c "from src.config import get_app_config; print('✓ Config loaded:', get_app_config().models[0].name)"
```
## Important Notes
- **Location**: `config.yaml` should be in `deer-flow/` (project root), not `deer-flow/backend/`
- **Git**: `config.yaml` is automatically ignored by git (contains secrets)
- **Priority**: If both `backend/config.yaml` and `../config.yaml` exist, backend version takes precedence
## Configuration File Locations
The backend searches for `config.yaml` in this order:
1. `DEER_FLOW_CONFIG_PATH` environment variable (if set)
2. `backend/config.yaml` (current directory when running from backend/)
3. `deer-flow/config.yaml` (parent directory - **recommended location**)
**Recommended**: Place `config.yaml` in project root (`deer-flow/config.yaml`).
## Troubleshooting
### Config file not found
```bash
# Check where the backend is looking
cd deer-flow/backend
python -c "from src.config.app_config import AppConfig; print(AppConfig.resolve_config_path())"
```
If it can't find the config:
1. Ensure you've copied `config.example.yaml` to `config.yaml`
2. Verify you're in the correct directory
3. Check the file exists: `ls -la ../config.yaml`
### Permission denied
```bash
chmod 600 ../config.yaml # Protect sensitive configuration
```
