+### Data Storage Backends
+
+Cosmium supports multiple storage backends for saving, loading, and managing data at runtime.
+
+| Backend  | Storage Location         | Write Behavior           | Memory Usage         | Supports Initial JSON Load |
+|----------|--------------------------|--------------------------|----------------------|----------------------------|
+| `json` (default) | JSON file on disk 📄 | On application exit ⏳ | 🛑 More than Badger | ✅ Yes                      |
+| `badger`  | BadgerDB database on disk ⚡ | Immediately on write 🚀 | ✅ Less than JSON  | ❌ No                       |
+
+
+The `badger` backend is generally recommended as it uses less memory and writes data to disk immediately. However, if you need to load initial data from a JSON file, use the `json` backend.
