-- Phase A: Repository & Configuration
-- Phase B/E: UI Layout (two-column design)
-- Phase C/G: World Bank API Integration
-- Phase D: Angular Routing Configuration
-- Phase F: SVG Interactivity & Event Binding
+### Phase A: Repository & Configuration ✅
+- Angular project initialization
+- README with Student ID and version information
+- All required configuration files (tsconfig.*.json, angular.json, package*.json)
+- SVG map asset integration
+
+### Phase D: Routing Configuration ✅
+- Root path (/) auto-redirects to /map
+- MapComponent routing
+- Angular Router implementation
+
+### Phase C/G: World Bank API Integration ✅
+- WorldBankService with HttpClient
+- Service method accepting 2-letter country codes
+- API endpoint: https://api.worldbank.org/v2/country/{code}
+- Component method triggering service calls
+
+### Phase E: UI Layout ✅
+- Two-column responsive design
+- Column 1: Interactive SVG world map
+- Column 2: Country data display panel
+- Loading, error, and placeholder states
+- Professional styling with card layout
+
+### Phase F: SVG Interactivity ✅
+- MapSvgComponent for inline SVG rendering
+- Event binding on country path elements
+- Click handlers extracting country codes
+- Hover effects with CSS transitions
+- Dynamic API calls on country selection
 
 ## Data Displayed (6 Properties)
 
-1. Country Name
-2. Country Capital
-3. Country Region
-4. Income Level
-5. [Custom Property 1]
-6. [Custom Property 2]
+1. **Country Name** - Official country name from World Bank
+2. **Capital** - Capital city
+3. **Region** - Geographic region classification
+4. **Income Level** - Economic income level classification
+5. **Longitude** *(Custom Property 1)* - Geographic longitude coordinate
+6. **Latitude** *(Custom Property 2)* - Geographic latitude coordinate
+
+## Features
+
+- **Interactive Map:** Click any country on the SVG map
+- **Real-time Data:** Fetches current country data from World Bank API
+- **Visual Feedback:** Hover effects show clickable countries
+- **Error Handling:** Graceful error messages for API failures
+- **Responsive Design:** Mobile-friendly two-column layout

 ## Getting Started
 
+### Installation
 ```bash
 npm install
-ng serve
 ```
 
-Navigate to `http://localhost:4200/`
-
-## Build
+### Development Server
+```bash
+ng serve
+```
+Navigate to `http://localhost:4200/` - automatically redirects to `/map`
 
+### Build
 ```bash
 ng build
 ```
-
 Build artifacts will be stored in the `dist/` directory.
