+
+The **Google A2A (Agent-to-Agent)**<sup>[View Repo](https://github.com/google/A2A)</sup> project defines an *open protocol* enabling different AI agents, possibly built with different technologies, to communicate and work together.
+Think of it as a common language (*A2A Protocol*) agents use to discover each other (*Agent Card*), assign work (*Task*), and exchange results, even providing real-time updates (*Streaming*).
+The project includes sample *client* and *server* implementations, example agents using frameworks like LangGraph or CrewAI, and a *demo UI* showcasing multi-agent interactions.
