+
+## Build Commands
+
+```bash
+# Debug build
+./gradlew assembleDebug
+# Output: app/build/outputs/apk/debug/app-debug.apk
+
+# Release build
+./gradlew assembleRelease
+
+# Run tests
+./gradlew test
+
+# Run Android instrumented tests (requires emulator/device)
+./gradlew connectedAndroidTest
+
+# Clean build
+./gradlew clean
+```
+
+## Requirements
+
+- JDK 17
+- Android SDK with API 34 (compileSdk)
+- Minimum supported Android: API 24 (Android 7.0)
+
+## Architecture
+
+This is a native Android WebView wrapper for Google Scholar (scholar.google.com) using Kotlin and Material Design 2.
+
+### Key Components
+
+- **MainActivity** (`ui/MainActivity.kt`): Single-activity architecture with navigation drawer, toolbar, and WebView. Implements listener interfaces for WebView callbacks.
+
+- **ScholarWebViewClient** (`webview/ScholarWebViewClient.kt`): Handles URL routing—Google Scholar and auth URLs load in-app, external URLs open in browser. Injects CSS for mobile experience improvements.
+
+- **ScholarUrls** (`util/ScholarUrls.kt`): Centralized URL constants and helper methods for URL validation and search URL generation.
+
+### Data Flow
+
+1. User interacts via navigation drawer → `onNavigationItemSelected()` → `loadUrl()`
+2. WebView loads URL → `ScholarWebViewClient` intercepts navigation
+3. Non-Scholar URLs trigger `onExternalUrlDetected()` → opens external browser
+4. Page state callbacks propagate to MainActivity via listener interfaces
+
+### View Binding
+
+Uses Android View Binding (`buildFeatures.viewBinding = true`). Layout bindings accessed via `binding.webView`, `binding.drawerLayout`, etc.
