+description: "Use Squads to handle complex workflows and tasks."
+---
+
+Sometimes, complex workflows are easier to manage with multiple assistants.
+For example, you might have one assistant for asking about personal information, and another for booking appointments.
+Each of these assistants can have their own configuration and may require drastically different prompts.
+
+Squads enable calls to transfer assistants mid-conversation, while maintaining full conversation context.
+
+## Usage
+
+To use Squads, you can create a `squad` when starting a call and specify `members` as a list of assistants and destinations.
+The first member is the assistant that will start the call, and assistants can be either persistent or transient.
+
+Each assistant should be assigned the relevant assistant transfer destinations.
+Transfers are specified by assistant name and are used when the model recognizes a specific trigger.

+    "squad": {
+        "members": [
+            {
+                "assistantId": "information-gathering-assistant-id",
+                "assistantDestinations": [{
+                    "type": "assistant",
+                    "assistantName": "Appointment Booking",
+                    "message": "Please hold on while I transfer you to our appointment booking assistant.",
+                    "description": "Transfer the user to the appointment booking assistant after they say their name."
+                }],
+            },
+            {
+                "assistant": {
+                    "name": "Appointment Booking",
+                    ...
+                },
+            }
+        ]
+    }
+}
+```

+
+## Best practices
+
+The following are some best practices for using Squads to reduce errors:
+
+- Group assistants by closely related tasks
+- Create as few assistants as possible to reduce complexity
+- Make sure descriptions for transfers are clear and concise
