-## Channel Status Tiers
+## Configuring a channel ("帮我配 XXX")
 
-- **Tier 0 (zero config):** Web, YouTube, RSS, Twitter (read-only via Jina)
-- **Tier 1 (free setup):** Exa web search (mcporter required)
-- **Tier 2 (user config):** Twitter search (cookie), Reddit full (proxy), GitHub (token), Bilibili (proxy), XiaoHongShu (MCP)
+All channels follow the same flow. When a user asks to configure/enable any channel:
 
-Run `agent-reach doctor` to see which channels are active.
+1. Run `agent-reach doctor`
+2. Find the channel in the output — it shows the current status (✅/⚠️/⬜) and **what to do next**
+3. Execute whatever you can automatically (install packages, start services, register MCP)
+4. For steps that require human action (scan QR code, paste cookies, login), tell the user exactly what to do
+5. After the user completes their part, run `agent-reach doctor` again to verify
+
+**Do NOT memorize per-channel steps.** Always rely on `doctor` output — it stays up-to-date even when backends change.
+
+### Common human actions
+
+These are things only the user can do. When `doctor` indicates one is needed, explain it clearly:
+
+- **Paste cookies:** User installs [Cookie-Editor](https://chromewebstore.google.com/detail/cookie-editor/hlkenndednhfkekhgcdicdfddnkalmdm) Chrome extension → goes to the website → exports Header String → sends it to you → you run `agent-reach configure <platform>-cookies "..."`
+- **Scan QR code:** User opens the URL shown in `doctor` output on their phone/browser and scans with the platform's app
+- **Browser login:** Some MCP services need a one-time browser login; on servers without a display, user may need VNC
+- **Proxy:** Reddit/Bilibili/XiaoHongShu block server IPs — suggest a residential proxy (~$1/month) if on a server
 
 ## Tips
 
 - Always try `agent-reach read <url>` first for any URL — it auto-detects the platform
-- For Twitter cookies, recommend the user install [Cookie-Editor](https://chromewebstore.google.com/detail/cookie-editor/hlkenndednhfkekhgcdicdfddnkalmdm) Chrome extension
-- Reddit and Bilibili block server IPs — suggest a residential proxy (~$1/month) if on a server
+- If a channel is ⬜ but the user hasn't asked for it, don't push — let them opt in
 - If a channel breaks, run `agent-reach doctor` to diagnose
+- LinkedIn and Boss直聘 have Jina Reader fallback even without full setup
