+# nanobot 🐈
+
+**nanobot** is an open-source, ultra-lightweight AI agent framework in the spirit of Claude Code, OpenClaw, and Codex. It keeps the core agent loop small and readable while delivering a production-ready personal agent experience.
+
+## What it does
+
+nanobot receives messages from chat channels, invokes an LLM of your choice, executes tools, and responds — all with persistent session memory and a minimal footprint.
+
+## Key capabilities
+
+- **15+ chat channels** — Telegram, Discord, Slack, WhatsApp, Feishu, Matrix, WeChat, WeCom, DingTalk, MS Teams, QQ, Email, MoChat, WebSocket
+- **Rich tool suite** — filesystem (read/write/edit), sandboxed shell, web search & fetch, MCP servers, cron scheduling, image generation, audio transcription, sub-agent spawning, notebook editing
+- **Persistent memory** — Dream two-phase memory consolidation with atomic session writes and TTL-based auto-compaction
+- **Long-horizon goals** — `/goal` command sustains objectives across many turns with visible multi-step progress
+- **Multi-provider** — Anthropic Claude, OpenAI, Azure OpenAI, AWS Bedrock, GitHub Copilot, DeepSeek, NVIDIA NIM, Hugging Face, Ollama, and more — with automatic fallback
+- **WebUI** — Vite/React SPA bundled inside the Python wheel; communicates over WebSocket multiplex
+- **OpenAI-compatible API** — `/v1/chat/completions` endpoint for programmatic access
+- **Plugin system** — channels and tools are auto-discovered via `pkgutil` and entry-point plugins
+
+## Installation & quick start
+
+```bash
+pip install nanobot-ai
+nanobot setup      # interactive wizard — pick your provider and model
+nanobot gateway    # start the gateway (Telegram, Discord, Slack, etc.)
+nanobot            # or run in terminal mode
+```
+
+## Architecture
+
+Messages flow through an async `MessageBus` that decouples channels from the agent core. The `AgentLoop` manages session keys and context; the `AgentRunner` executes the multi-turn LLM conversation with tool calls. Every capability lives at the edge (channels, tools, MCP) — the core stays small.
