AG2's open-source multi-agent runtime. Build hubs, register agents, open channels, plug in your own adapters, and add rules.
Eight short pages. By the end you'll have walked through a working hub, three turn-taking adapters, hub-side governance, and the protocol for writing your own. Every page teaches one concept with the actual autogen.beta.network primitives, and ships a runnable code example tested end-to-end with Gemini — fork it, edit it, run it.
ChannelAdapter protocol and a custom adapter, ~50 lines.
