+# Microsoft.Bot.Builder.AI.Orchestrator
+
+Embedded recognizer package for detecting and routing user intents. 
+
+## Getting started
+
+To use Orchestrator is an intent router:
+
+1. Install this Orchestrator package.
+2. Select it as the dialog recognizer where you want to perform the routing.
+3. Author your LU as you would normally do for **intents only**. 
+4. Connect your intents to subsequent handlers such as skills, or LUIS dialogs. 
+
+## Notes
+* Orchestrator is highly recommended and is the default recognizer when creating multi-bot solutions or when adding a remote skill. 
+* You may use Orchestrator for intent detection only as you would for routing or if entity extraction is not required.
+* Orchestrator does not process entity declarations or does any entity extraction today.
