-## Configuration
+## Advanced Usage
 
-PUMA stores models in `~/.puma/cache` by default. This location is used for all downloaded models and metadata.
+### Pattern Matching
 
-## Supported Providers
+```bash
+# Substring match
+puma ls qwen
 
-- **Hugging Face** - Full support with custom cache directories
+# Prefix match
+puma ls "^inftyai/"
 
-## Development
+# Alternation
+puma ls "llama-(2|3)"
+```
 
-### Build
+### Label Filtering
 
 ```bash
-make build
+# Single filter
+puma ls -l author=inftyai
+
+# Multiple filters (AND condition)
+puma ls -l author=inftyai,license=mit
+
+# Combine pattern + filter
+puma ls llama -l author=meta
 ```
 
-### Test
+**Available filters:** `author`, `task`, `license`, `provider`, `model_series`
+
+### Inspect Output
 
 ```bash
+$ puma inspect inftyai/tiny-random-gpt2
+
+name: inftyai/tiny-random-gpt2
+kind: model
+spec:

+
+## Model Management
+
+- **Database:** `~/.puma/models.db` (SQLite)
+- **Cache:** `~/.puma/cache/` (model files)
+
+Models are stored with lowercase names for case-insensitive matching.
