+Presets allow you to save, share, and reuse configurations easily. You can export your current configuration as a preset and install presets from files or URLs.
+
+```shell
+# Export current configuration as a preset
+ccr preset export my-preset
+
+# Export with metadata
+ccr preset export my-preset --description "My OpenAI config" --author "Your Name" --tags "openai,production"
+
+# Install a preset from file, URL, or registry
+ccr preset install my-preset.ccrsets
+ccr preset install https://example.com/preset.ccrsets
+
+# List all installed presets
+ccr preset list
+
+# Show preset information
+ccr preset info my-preset
+
+# Delete a preset
+ccr preset delete my-preset
+```

+**Preset Features:**
+- **Export**: Save your current configuration as a `.ccrsets` file (ZIP archive with manifest.json)

+- **Dynamic Configuration**: Presets can include input schemas for collecting required information during installation
+- **Version Control**: Each preset includes version metadata for tracking updates
