+### 3. Create Labels (Automatic Setup)
+
+**Option A: Automatic Setup (Recommended)**
+
+Create an issue and comment:
+```
+@codebot setup-labels
+```
+
+The bot will automatically:
+- Detect your existing label schema (e.g., `Kind/Bug`, `Priority - High`)
+- Map existing labels to OpenRabbit's auto-labeling system
+- Create only the missing labels you need
+- Follow your repository's naming convention
+
+**Option B: Manual Setup**
 
 Create these labels in your repository for auto-labeling:
-- `priority: high`, `priority: medium`, `priority: low`
-- `type: bug`, `type: feature`, `type: question`
-- `ai-approved`, `ai-changes-required`
+- `priority: critical`, `priority: high`, `priority: medium`, `priority: low`
+- `type: bug`, `type: feature`, `type: question`, `type: documentation`
+- `ai-approved`, `ai-changes-required`, `ai-reviewed`

+### Label Setup Command
+
+The `@codebot setup-labels` command intelligently detects your existing label schema and sets up auto-labeling:
+
+**For repositories with existing labels (e.g., `Kind/Bug`, `Priority - High`):**
+- Detects your naming pattern (prefix/slash, prefix-dash, or colon-style)
+- Maps your existing labels to OpenRabbit's schema
+- Creates only missing labels following your pattern
+- Zero duplicate labels created
+
+**For fresh repositories:**
+- Creates OpenRabbit's default label set
+- Uses `type:`, `priority:`, and status labels
+
+**Example output:**
+```
+@codebot setup-labels
+
+✅ Found 18 existing labels with pattern: prefix_slash
+
+Detected Categories:
+- Kind (7 labels): Bug, Feature, Documentation, Security, Testing
+- Priority (4 labels): Critical, High, Medium, Low
+
+Proposed Mapping:
+| OpenRabbit Expected | Your Existing Label | Status |
+|---------------------|---------------------|--------|
+| type: bug          | Kind/Bug            | ✅ Map |
+| priority: high     | Priority - High     | ✅ Map |
+| ai-reviewed        | (missing)           | ⚠️ Create |
+
+✅ Created Kind/Question (#cc317c)
+✅ Created Status - AI Reviewed (#1d76db)
+
+Setup Complete! Auto-labeling will use your existing label schema.
