 # Contributing to nanobot
 Thank you for being here.
 nanobot is built with a simple belief: good tools should feel calm, clear, and humane.
 We care deeply about useful features, but we also believe in achieving more with less:
 solutions should be powerful without becoming heavy, and ambitious without becoming
 needlessly complicated.
 This guide is not only about how to open a PR. It is also about how we hope to build
 software together: with care, clarity, and respect for the next person reading the code.
 ## Maintainers
 | Maintainer | Focus |
 |------------|-------|
 | [@re-bin](https://github.com/re-bin) | Project lead, `main` branch |
 | [@chengyongru](https://github.com/chengyongru) | `nightly` branch, experimental features |
 ## Branching Strategy
 We use a two-branch model to balance stability and exploration:
 | Branch | Purpose | Stability |
 |--------|---------|-----------|
 | `main` | Stable releases | Production-ready |
 | `nightly` | Experimental features | May have bugs or breaking changes |
 ### Which Branch Should I Target?
 **Target `nightly` if your PR includes:**
 - New features or functionality
 - Refactoring that may affect existing behavior
 - Changes to APIs or configuration
 **Target `main` if your PR includes:**
 - Bug fixes with no behavior changes
 - Documentation improvements
 - Minor tweaks that don't affect functionality
 **When in doubt, target `nightly`.** It is easier to move a stable idea from `nightly`
 to `main` than to undo a risky change after it lands in the stable branch.
 ### How Does Nightly Get Merged to Main?
 We don't merge the entire `nightly` branch. Instead, stable features are **cherry-picked** from `nightly` into individual PRs targeting `main`:
 ```
 nightly  ──┬── feature A (stable) ──► PR ──► main
           ├── feature B (testing)
           └── feature C (stable) ──► PR ──► main
 ```
 This happens approximately **once a week**, but the timing depends on when features become stable enough.
 ### Quick Summary
 | Your Change | Target Branch |
 |-------------|---------------|
 | New feature | `nightly` |
 | Bug fix | `main` |
 | Documentation | `main` |
 | Refactoring | `nightly` |
 | Unsure | `nightly` |
 ## Development Setup
 Keep setup boring and reliable. The goal is to get you into the code quickly:
 ```bash
 # Clone the repository
 git clone https://github.com/HKUDS/nanobot.git
 cd nanobot
 # Install with dev dependencies
 pip install -e ".[dev]"
 # Run tests
 pytest
 # Lint code
 ruff check nanobot/
 # Format code
 ruff format nanobot/
 ```
 ## Code Style
 We care about more than passing lint. We want nanobot to stay small, calm, and readable.
 When contributing, please aim for code that feels:
 - Simple: prefer the smallest change that solves the real problem
 - Clear: optimize for the next reader, not for cleverness
 - Decoupled: keep boundaries clean and avoid unnecessary new abstractions
 - Honest: do not hide complexity, but do not create extra complexity either
 - Durable: choose solutions that are easy to maintain, test, and extend
 In practice:
 - Line length: 100 characters (`ruff`)
 - Target: Python 3.11+
 - Linting: `ruff` with rules E, F, I, N, W (E501 ignored)
 - Async: uses `asyncio` throughout; pytest with `asyncio_mode = "auto"`
 - Prefer readable code over magical code
 - Prefer focused patches over broad rewrites
 - If a new abstraction is introduced, it should clearly reduce complexity rather than move it around
 ## Questions?
 If you have questions, ideas, or half-formed insights, you are warmly welcome here.
 Please feel free to open an [issue](https://github.com/HKUDS/nanobot/issues), join the community, or simply reach out:
 - [Discord](https://discord.gg/MnCvHqpUGB)
 - [Feishu/WeChat](./COMMUNICATION.md)
 - Email: Xubin Ren (@Re-bin) — <xubinrencs@gmail.com>
 Thank you for spending your time and care on nanobot. We would love for more people to participate in this community, and we genuinely welcome contributions of all sizes.

+Run multiple nanobot instances simultaneously with separate configs and runtime data. Use `--config` as the main entrypoint. Optionally pass `--workspace` during `onboard` when you want to initialize or update the saved workspace for a specific instance.
 ### Quick Start
 If you want each instance to have its own dedicated workspace from the start, pass both `--config` and `--workspace` during onboarding.
 **Initialize instances:**
 ```bash
 # Create separate instance configs and workspaces
 nanobot onboard --config ~/.nanobot-telegram/config.json --workspace ~/.nanobot-telegram/workspace
 nanobot onboard --config ~/.nanobot-discord/config.json --workspace ~/.nanobot-discord/workspace
 nanobot onboard --config ~/.nanobot-feishu/config.json --workspace ~/.nanobot-feishu/workspace
 ```
 **Configure each instance:**
 Edit `~/.nanobot-telegram/config.json`, `~/.nanobot-discord/config.json`, etc. with different channel settings. The workspace you passed during `onboard` is saved into each config as that instance's default workspace.
