+# Commit 13: Remove Channel Setup Step
+
+## Overview
+Simplified the setup wizard by removing the channel connection step. Users can now start using ClawX immediately and configure messaging channels later in Settings.
+
+## Rationale
+- Channel connection (WhatsApp, Telegram, etc.) is complex and requires external platform configuration
+- Not required for core functionality - users can use the built-in chat interface directly
+- Reduces onboarding friction for new users
+- Progressive disclosure - advanced features available when needed
+
+## Changes
+
+### 1. Setup Wizard (`src/pages/Setup/index.tsx`)
+
+**Steps reduced from 6 to 5:**
+
+| Before | After |
+|--------|-------|
+| 0: Welcome | 0: Welcome |
+| 1: Runtime | 1: Runtime |
+| 2: Provider | 2: Provider |
+| 3: Channel | (removed) |
+| 4: Skills | 3: Skills |
+| 5: Complete | 4: Complete |
+
+**Code changes:**
+- Removed `channel` step from `steps` array
+- Updated `currentStep` indices for content rendering
+- Updated `useEffect` for `canProceed` validation
+- Removed `selectedChannel` state variable
+- Removed `ChannelContent` component and `Channel` interface
+- Updated `CompleteContent` to remove channel row
+- Added note about configuring channels in Settings
+
+### 2. Architecture Document (`ClawX-项目架构与版本大纲.md`)
+
+- Updated section 2.4.2 setup wizard steps (removed ChannelStep)
+- Updated directory structure (added ChannelsSettings.tsx to Settings, removed ChannelStep.tsx)
+- Updated v0.5.0 milestone to note channel connection is deferred
+
+## User Experience
+
+**Before:**
+```
+Welcome → Runtime → Provider → Channel → Skills → Complete
+                                  ↑
+                          (complex, often skipped)
+```
+
+**After:**
+```
+Welcome → Runtime → Provider → Skills → Complete
+                                          ↓
+                              "Configure channels in Settings"
+```
+
+## Files Changed
+- `src/pages/Setup/index.tsx` - Removed channel step (-140 lines)
+- `ClawX-项目架构与版本大纲.md` - Updated documentation
+
+## Future Work
+- Implement Settings > Channels page with:
+  - WhatsApp QR code scanning
+  - Telegram bot token configuration
+  - Discord/Slack OAuth flows
+  - Connection status indicators
