docs: make onboarding friendlier for beginners (#4177)
* docs: make onboarding friendlier for beginners

* docs: build clearer documentation paths

Maintainer edit: turn the onboarding follow-up into a layered docs structure for first-time setup, provider selection, troubleshooting, CLI reference, and source-level architecture. This keeps quick start focused while giving advanced users precise reference paths.

* docs: render architecture flow with mermaid

Maintainer edit: replace the ASCII architecture sketch with a GitHub-rendered Mermaid flowchart so the core runtime path is easier to scan in the PR and README docs.

* docs: recommend model presets for model config

Maintainer edit: make named modelPresets the primary model configuration path and expand fallback preset examples so string fallbacks are clearly preset names, not raw model IDs.

* docs: document api base urls and langfuse setup

Maintainer edit: explain when users need apiBase/base URL in quick start and provider docs, and add Langfuse tracing setup with troubleshooting links.

* docs: use python module pip consistently

Maintainer edit: keep install commands tied to the active Python interpreter by using python -m pip in the Azure optional dependency notes too.

* docs: add non-technical getting started path

Maintainer edit: add a wizard-first guide for users without terminal or JSON background, including a text TUI menu example and links from the main docs entrypoints.

* docs: avoid hard-wrapped prose in user docs

Maintainer edit: unwrap ordinary prose across user-facing documentation while preserving markdown structure, code blocks, tables, lists, and prompt/template files.

* docs: keep desktop list continuations nested

Maintainer edit: preserve list nesting after unwrapping prose in the desktop WebUI sync guide.

* docs: add one-command installer

Maintainer edit: add auditable macOS/Linux and Windows install scripts that install nanobot-ai and start the onboarding wizard, then document the commands in the main onboarding entrypoints.

* docs: add installer dry run mode

Maintainer edit: add --dry-run to the one-command installer scripts so users can preview Python detection, install source, pip command, and wizard behavior without changing their environment.

* docs: clean installer error output

Maintainer edit: make PowerShell installer failures print a concise Error: message instead of Write-Error call-site details.

* docs: add provider setup cookbook

Maintainer edit: add pasteable provider recipes for common hosted, local, fallback, runtime switching, and Langfuse setups, then link the cookbook from onboarding and troubleshooting entrypoints.

* docs: address review feedback

* docs: clarify reader paths

* docs: explain terminal basics for beginners

* docs: clarify wizard navigation

* docs: avoid duplicate onboarding steps

* docs: add setup status check

* docs: explain status output

* docs: remove provider recommendation wording

* docs: explain status diagnostics

* docs: reduce hard-wrapped guidance

* docs: migrate config examples to presets

* docs: clarify python command fallbacks

* docs: improve installer failure recovery

* docs: expand install troubleshooting

* docs: cover installer download failures

* docs: put stable install paths first

* docs: add bundled webui quick path

* docs: clarify provider-neutral setup

* docs: clarify gateway setup for chat surfaces

* docs: improve docs navigation paths

* docs: add configuration quick jump

* docs: clarify provider secret variables

* chore: request PR review acknowledgement

Empty commit: please read the PR review comments and reply on the PR to confirm that you have received them.

This commit intentionally changes no files; it exists only to notify the remote Codex run so it can end its active goal.

* docs: add README start here guide

* docs: avoid provider recommendation wording

* docs: guide next steps after first reply

* docs: explain merging JSON snippets

* docs: add CLI command chooser

* docs: add configuration task map

* docs: add deployment readiness guide

* docs: simplify WebUI entry paths

* docs: add provider recipe chooser

* docs: fix provider factual references

Update OpenRouter and LongCat model examples, align Bedrock guidance, and make fallback snippets schema-valid.

Also correct group policy wording and image-generation provider lists to match the current code.

* fix: keep PowerShell installer from closing caller shell

* docs: mention self-guided configuration

# Multiple Instances
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.
**Run instances:**
```bash
# Instance A - Telegram bot
nanobot gateway --config ~/.nanobot-telegram/config.json
# Instance B - Discord bot
nanobot gateway --config ~/.nanobot-discord/config.json
# Instance C - Feishu bot with custom port
nanobot gateway --config ~/.nanobot-feishu/config.json --port 18792
```
## Path Resolution
When using `--config`, nanobot derives its runtime data directory from the config file location. The workspace still comes from `agents.defaults.workspace` unless you override it with `--workspace`.
To open a CLI session against one of these instances locally:
```bash
nanobot agent -c ~/.nanobot-telegram/config.json -m "Hello from Telegram instance"
nanobot agent -c ~/.nanobot-discord/config.json -m "Hello from Discord instance"
# Optional one-off workspace override
nanobot agent -c ~/.nanobot-telegram/config.json -w /tmp/nanobot-telegram-test
```
> `nanobot agent` starts a local CLI agent using the selected workspace/config. It does not attach to or proxy through an already running `nanobot gateway` process.
| Component | Resolved From | Example |
|-----------|---------------|---------|
| **Config** | `--config` path | `~/.nanobot-A/config.json` |
| **Workspace** | `--workspace` or config | `~/.nanobot-A/workspace/` |
| **Cron Jobs** | workspace directory | `~/.nanobot-A/workspace/cron/` |
| **Media / runtime state** | config directory | `~/.nanobot-A/media/` |
## How It Works
- `--config` selects which config file to load
- By default, the workspace comes from `agents.defaults.workspace` in that config
- If you pass `--workspace`, it overrides the workspace from the config file
## Minimal Setup
1. Copy your base config into a new instance directory.
2. Set a different `agents.defaults.workspace` for that instance.
3. Start the instance with `--config`.
Example config fragment:
```json
{
"agents": {
"defaults": {
"workspace": "~/.nanobot-telegram/workspace"
}
},
"channels": {
"telegram": {
"enabled": true,
"token": "YOUR_TELEGRAM_BOT_TOKEN"
}
},
"gateway": {
"host": "127.0.0.1",
"port": 18790
}
}
```
The copied base config can keep using the same `modelPresets` and `agents.defaults.modelPreset`. If this instance needs a different model, add another preset and set `agents.defaults.modelPreset` to that preset name.
Start separate instances:
```bash
nanobot gateway --config ~/.nanobot-telegram/config.json
nanobot gateway --config ~/.nanobot-discord/config.json
```
Each gateway instance also exposes a lightweight HTTP health endpoint on `gateway.host:gateway.port`. By default, the gateway binds to `127.0.0.1`, so the endpoint stays local unless you explicitly set `gateway.host` to a public or LAN-facing address.
- `GET /health` returns `{"status":"ok"}`
- Other paths return `404`
Override workspace for one-off runs when needed:
```bash
nanobot gateway --config ~/.nanobot-telegram/config.json --workspace /tmp/nanobot-telegram-test
```
## Common Use Cases
- Run separate bots for Telegram, Discord, Feishu, and other platforms
- Keep testing and production instances isolated
- Use different models or providers for different teams
- Serve multiple tenants with separate configs and runtime data
## Notes
- Each instance must use a different port if they run at the same time
- Use a different workspace per instance if you want isolated memory, sessions, and skills
- `--workspace` overrides the workspace defined in the config file
- Cron jobs are stored in the active workspace; runtime media/state is derived from the config directory
