+
+```yaml
+---

+emoji: ✍️
+colorFrom: blue
+colorTo: purple
+sdk: gradio
+sdk_version: 4.0.0
+app_file: app.py

+**Higher tiers available** for more demanding workloads
+
+## Customizing Your Space
+
+### Method 1: Edit YAML Frontmatter
+
+1. Open your Space on HuggingFace
+2. Click "Files" tab
+3. Edit `README.md`
+4. Modify YAML frontmatter
+5. Commit changes
+
+Example customizations:
+
+```yaml
+---
+# Change display
+title: My Custom Writing Studio
+emoji: 📝
+colorFrom: green
+colorTo: blue
+
+# Upgrade hardware suggestion
+suggested_hardware: t4-small
+
+# Pin to profile
+pinned: true
+---
+```
+
+### Method 2: Environment Variables
+
+For application settings (not Space config), use Settings → Variables:
+
+```
+DEFAULT_MODEL=gpt2
+MAX_TEXT_LENGTH=5000
+LOG_LEVEL=DEBUG
+ENABLE_CACHE=true
+```
+
+## Common Configurations
+
+### Free Tier Optimized (Default)
+
+```yaml
+---
+sdk: gradio
+sdk_version: 4.0.0
+suggested_hardware: cpu-basic
+suggested_storage: small
+---
+```
+
+With environment variables:
+```
+DEFAULT_MODEL=distilgpt2
+ENABLE_CACHE=true
+```
+
+### GPU Accelerated
+
+```yaml
+---
+sdk: gradio
+sdk_version: 4.0.0
+suggested_hardware: t4-small
+suggested_storage: medium
+---
+```
+
+With environment variables:
+```
+DEFAULT_MODEL=gpt2-medium
+ENABLE_CACHE=true
+CACHE_MAX_SIZE=200
+```
+
+### High Performance
+
+```yaml
+---
+sdk: gradio
+sdk_version: 4.0.0
+suggested_hardware: a10g-small
+suggested_storage: large
+---
+```
+
+With environment variables:
+```
+DEFAULT_MODEL=gpt2-large
+ENABLE_CACHE=true
+CACHE_MAX_SIZE=500
+```
+
+## Advanced Options
+
+### Full-Width Display
+
+```yaml
+---
+fullWidth: true
+---
+```
+
+### Mini Header
+
+```yaml
+---
+header: mini
+---
+```
+
+### Custom Models/Datasets
+
+```yaml
+---
+models:
+  - distilgpt2
+  - gpt2
+datasets:
+  - your-dataset-name
+---
+```
+
+### OAuth Integration
+
+```yaml
+---
+hf_oauth: true
+hf_oauth_scopes:
+  - read-repos
+  - write-repos
+hf_oauth_expiration_minutes: 480
+---
+```
+
+### Disable Embedding
+
+```yaml
+---
+disable_embedding: true
+---
+```
+
+## Environment Variables Reference
+
+These go in Space Settings → Variables, NOT in YAML:
+
+| Variable | Default | Description |
+|----------|---------|-------------|
+| `ENVIRONMENT` | `production` | Runtime environment |
+| `DEBUG` | `false` | Debug mode |
+| `LOG_LEVEL` | `INFO` | Logging level |
+| `DEFAULT_MODEL` | `distilgpt2` | HuggingFace model ID |
+| `MAX_TEXT_LENGTH` | `10000` | Max input characters |
+| `ENABLE_CACHE` | `true` | Enable result caching |
+| `CACHE_MAX_SIZE` | `100` | Cache entry limit |
+| `ENABLE_METRICS` | `false` | Prometheus metrics |
+| `LOG_FORMAT` | `text` | Log format (json/text) |
+
+## Troubleshooting
+
+### Configuration Not Applied
+
+1. Check YAML syntax (spaces matter!)
+2. Ensure YAML is at top of README.md
+3. Must be between `---` delimiters
+4. Commit changes and wait for rebuild
+
+### Hardware Not Changed
+
+- `suggested_hardware` is only a suggestion
+- Doesn't automatically assign hardware
+- Users must manually select tier in Settings
+- Useful for Spaces meant to be duplicated
+
+### Environment Variables Not Working
+
+- Set in Settings → Variables (not in YAML)
+- May need to restart Space
+- Check logs for confirmation
+
+## Best Practices
+
+1. **Start with defaults** - They work well for most cases
+2. **Test locally first** - `python app.py`
+3. **Use free tier initially** - Upgrade only if needed
+4. **Set suggested_hardware** - Helps duplicators
+5. **Add descriptive tags** - Improves discoverability
+6. **Write good short_description** - Shows in thumbnail
+7. **Keep emoji relevant** - Helps users identify your Space
