+# Open Source Quickstart (Windows)
+
+This guide is the shortest path for first-time users.
+
+## Prerequisites
+
+- Python 3.11+
+- Node.js 22+
+- PowerShell (Windows 10/11)
+
+## Path A: Web/Admin only (no Weixin/WhatsApp required)
+
+1) Bootstrap Python venv:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\scripts\bootstrap_venv.ps1
+```
+
+2) Start full stack in background:
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\scripts\start_all.ps1 -Background
+```
+
+3) Open:
+
+- Admin: `http://127.0.0.1:8787/admin`
+- Chat: `http://127.0.0.1:8787/chat`
+
+Notes:
+
+- If Weixin/WhatsApp sidecars are not installed, `start_all.ps1` will skip them with a warning and continue.
+- This does not block Admin/Chat.
+
+## Path B: Enable Weixin (Personal WeChat)
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\runtime\operations\scripts\weixin_install.ps1 -UseOpenclawCli
+powershell -ExecutionPolicy Bypass -File .\runtime\operations\scripts\weixin_login.ps1
+powershell -ExecutionPolicy Bypass -File .\runtime\operations\scripts\weixin_start.ps1
+```
+
+Notes:
+
+- No global `openclaw` CLI installation is required.
+- Runtime dependencies are installed locally in sidecar workspace.
+
+## Path C: Enable WhatsApp (experimental)
+
+```powershell
+powershell -ExecutionPolicy Bypass -File .\runtime\operations\scripts\whatsapp_install.ps1
+powershell -ExecutionPolicy Bypass -File .\runtime\operations\scripts\whatsapp_login.ps1
+powershell -ExecutionPolicy Bypass -File .\runtime\operations\scripts\whatsapp_start.ps1
+```
+
+## Admin dispatch controls (Weixin/WhatsApp)
+
+In Admin:
+
+- `Stack` page: channel-level controls (`Bind specialist` / `Comprehensive`)
+- `User/Channel binding` page: account-level controls per channel/account
+
+Priority:
+
+1. Account-level dispatch config
+2. Channel-level dispatch config
+3. Default (`expert + generalist`)
+
+## Common commands
+
+Start:
+
+```powershell
+.\scripts\start_all.ps1 -Background
+```
+
+Status:
+
+```powershell
+.\scripts\status_all.ps1
+```
+
+Stop:
+
+```powershell
+.\scripts\stop_all.ps1
+```
+
+Force stop:
+
+```powershell
+.\scripts\stop_all.ps1 -Force
+```
+
