 - **Internet connection** for real-time data sync
 
 ## 🎯 How It Works
 
-Vibe Meter connects securely to your Cursor AI account and monitors your monthly usage:
+Vibe Meter monitors your AI service usage through different methods:
 
+### Cursor AI
+- **Secure Login** - Connects via official web authentication
+- **API Integration** - Fetches usage data directly from Cursor's servers
 - **Automatic Sync** - Updates spending data every 5 minutes
+
+### Claude
+- **Local Log Analysis** - Reads usage data from `~/.claude/projects/` with your permission
+- **No Login Required** - Select your account type (Free/Pro) in settings
+- **5-Hour Window Tracking** - Monitors Claude Pro's rolling quota in real-time
+- **Token Counting** - Uses OpenAI's o200k_base encoding for accurate calculations
+
+### All Providers
 - **Visual Indicators** - Gauge fills up as you approach your spending limits
 - **Progress Notifications** - Alerts at 80% and 100% of your warning threshold
 - **Currency Conversion** - Real-time exchange rates for accurate international tracking
 
 ### 📊 Gauge Behavior
 
-The gauge icon in the menu bar adapts its display based on your usage:
+The gauge icon in the menu bar has two display modes:
 
+#### Total Spending Mode (Default)
 - **No Money Spent** - When you haven't spent any money yet (but have used requests), the gauge shows the percentage of API requests used. For example, if you've used 3 out of 500 requests, the gauge shows 0.6% filled.
 - **Money Spent** - Once you start spending money, the gauge switches to show spending as a percentage of your upper limit. For example, if you've spent $15 out of a $30 limit, the gauge shows 50% filled.
 
-This intelligent behavior ensures the gauge always provides meaningful feedback about your usage, whether you're on a free tier using requests or actively spending on premium features.
+#### Claude Quota Mode (Optional)
+- **5-Hour Window** - For Claude Pro users, the gauge can show your remaining quota in the 5-hour rolling window
+- **Real-time Updates** - The gauge updates as you use Claude, showing how much of your quota remains
+- **Toggle in Settings** - Switch between spending and quota display modes in General Settings
+
+This intelligent behavior ensures the gauge always provides meaningful feedback about your usage, whether you're tracking overall spending or Claude's specific quota limits.
+
+## 🧪 Testing & Code Coverage
+
+VibeMeter maintains comprehensive test coverage to ensure reliability:
+
+### Running Tests
+```bash
+# Run all tests
+xcodebuild test -workspace VibeMeter.xcworkspace -scheme VibeMeter

+./scripts/generate-coverage-report.sh --html --open
+
+# Enforce minimum coverage threshold
+./scripts/generate-coverage-report.sh --min-coverage 70

+
+### Test Coverage
+- **Current Coverage**: ~80-85%
+- **Test Files**: 40+ test suites
+- **Test Categories**:
+  - Unit tests for business logic
+  - Integration tests for provider workflows
+  - UI component tests (with ViewInspector)
+  - Performance benchmarks
+
+### Continuous Integration
+Code coverage is automatically generated and reported on all pull requests via GitHub Actions.
