+## Multiple Marketplace Registrations
+
+For enterprise and team scenarios, you can register multiple plugin marketplaces
+with different loading strategies. This allows you to:
+
+- Register internal team marketplaces alongside the public marketplace
+- Control which plugins auto-load at conversation start vs load on-demand
+- Reference plugins from specific marketplaces using the `plugin@marketplace` syntax
+
+### Loading Strategies
+
+| Strategy | Behavior |
+|----------|----------|
+| `auto_load="all"` | All plugins from the marketplace load automatically when a conversation starts |
+| `auto_load=None` (default) | Marketplace is registered but plugins are loaded on-demand via `load_plugin()` |
+
+### Plugin Reference Syntax
+
+Use the `plugin-name@marketplace-name` format to explicitly specify which
+marketplace a plugin comes from. This syntax follows the same convention as
+[Claude Code's plugin install command](https://code.claude.com/docs/en/plugins-reference).
+
+```python icon="python"
+# Load a specific plugin from a registered marketplace
+conversation.load_plugin("greeter@demo")
+
+# If only one marketplace has the plugin, the marketplace name is optional
+conversation.load_plugin("greeter")
+```
+
+### Example: Auto-load and On-demand Loading
+
+The example below demonstrates registering two marketplaces with different
+loading strategies, then loading an additional plugin on-demand.
