+
+## 🔧 Installation & Setup
+
+### Prerequisites
+- Modern web browser (Chrome, Firefox, Safari, Edge)
+- Web server (Apache, Nginx, or development server)
+- Perl 5.x (for server-side functionality)
+- npm (Node.js package manager)
+
+### Installation Steps
+```bash
+# Clone the repository
+git clone https://github.com/anisharma07/socialcalc.git
+
+# Navigate to project directory
+cd socialcalc
+
+# Install dependencies
+npm install
+
+# Set up web server to serve static files
+# Point document root to the socialcalc directory
+
+# For Perl server components (optional)
+perl -c SocialCalcServersideUtilities.pm
+```
+
+## 🎯 Usage
+
+### Development
+```bash
+# Serve files using a simple HTTP server
+# Python 3
+python -m http.server 8000
+
+# Python 2
+python -m SimpleHTTPServer 8000
+
+# Node.js (if http-server is installed)
+npx http-server
+
+# Access demos at:
+# http://localhost:8000/socialcalc2demo-0-8-1.html
+# http://localhost:8000/socialcalc2demo10.html
+# http://localhost:8000/ssctrltest1.html
+```
+
+### Production
+```bash
+# Deploy static files to web server
+cp -r socialcalc/ /var/www/html/
+
+# Configure server to serve .pl files (for Perl backend)
+# Ensure CGI is enabled for Perl scripts
+# Set appropriate permissions for .pl files
+chmod +x *.pl
+```
+
+### Integration
+```javascript
+// Basic SocialCalc integration
+// Include required JavaScript files in your HTML:
+<script src="socialcalcconstants.js"></script>
+<script src="socialcalc-3.js"></script>
+<script src="socialcalctableeditor.js"></script>
+<script src="formatnumber2.js"></script>
+<script src="formula1.js"></script>
+<script src="socialcalcpopup.js"></script>
+<script src="socialcalcspreadsheetcontrol.js"></script>
+
+// Initialize spreadsheet
+var spreadsheet = new SocialCalc.SpreadsheetControl();
+spreadsheet.InitializeSpreadsheetControl("container-id");
+```
+
+## 📱 Platform Support
+
+- **Web Browsers**: Chrome, Firefox, Safari, Edge, Internet Explorer 8+
+- **Operating Systems**: Windows, macOS, Linux (via web browser)
+- **Mobile**: iOS Safari, Android Chrome (responsive design)
+- **Server Platforms**: Linux, Unix, Windows (for Perl backend)
+
+## 🧪 Testing
+
+```bash
+# Run basic functionality tests
+# Open test files in browser:
+# - ssctrltest1.html (Spreadsheet control test)
+# - socialcalc2demo-0-8-1.html (Demo application)
+# - socialcalc2demo10.html (Advanced demo)
+
+# Manual testing checklist:
+# 1. Cell editing and navigation
+# 2. Formula calculation
+# 3. Copy/paste operations
+# 4. Formatting functions

+# Enable mod_cgi or mod_cgid in Apache
+# Set up proper permissions for .pl scripts
+
+# Test Perl components
+perl -c simpleedit14.pl
+perl -c simpleedit15.pl
+perl -c socialcalcserver.pl
+```
+
