docs: update terminology in documentation

- Update documentation to use "Digi-ID" instead of "DigiID" in user-facing text
- Maintain internal code using 'DigiID' for consistency with original implementation

The changes improve documentation clarity while maintaining full functionality.

 ## Installation
 
-As this package is not yet published on NPM, you can install it directly from GitHub:
-
 ```bash
-npm install pawelzelawski/digiid-ts
-# or using yarn
-yarn add pawelzelawski/digiid-ts
-# or using pnpm
-pnpm add pawelzelawski/digiid-ts
+npm install digiid-ts
 ```
 
 ## Usage
 
-### Generating a DigiID URI
-
-Typically used on the server-side to generate a unique URI for each login attempt.
+### Generating a Digi-ID URI
 
 ```typescript
 import { generateDigiIDUri, DigiIDError } from 'digiid-ts';
 
-// Define options for the URI
 const options = {
-  // Your backend endpoint URL where the wallet will POST the signed data
-  // **Must be a full URL including the scheme (e.g., 'https://' or 'http://')**
-  callbackUrl: 'https://yourdomain.com/api/digiid/callback',
-  // Optional: Provide your own cryptographically secure nonce
-  // nonce: 'your-securely-generated-nonce',
-  // Optional: Set to true only for testing with HTTP callback URL (default: false)
-  // unsecure: false,
+  callbackUrl: 'https://your-site.com/auth/callback',
+  // Optional parameters:
+  nonce: 'custom-nonce', // Defaults to random UUID
+  unsecure: false, // Defaults to false (requires HTTPS)
 };
 
 try {
   const digiidUri = generateDigiIDUri(options);
-  console.log('Generated DigiID URI:', digiidUri);
-  // Example output: digiid://yourdomain.com/api/digiid/callback?x=GENERATED_NONCE&u=0
-
-  // Now, display this URI as a QR code for the user to scan.
-  // You can use libraries like 'qrcode' for this.
-
+  console.log('Generated Digi-ID URI:', digiidUri);
+  // Display this URI as a QR code for the user to scan
 } catch (error) {
   if (error instanceof DigiIDError) {
-    console.error('Failed to generate DigiID URI:', error.message);
-  } else {
-    console.error('An unexpected error occurred:', error);
+    console.error('Failed to generate Digi-ID URI:', error.message);
   }
 }
 ```
 
-### Verifying the DigiID Callback
-
-When the user scans the QR code and approves, their wallet sends a POST request to your `callbackUrl`. Your backend needs to verify this data.
+### Verifying the Digi-ID Callback
 
 ```typescript
 import { verifyDigiIDCallback, DigiIDError, DigiIDCallbackData } from 'digiid-ts';
 
-// Example using Express.js - adapt for your framework
-app.post('/api/digiid/callback', async (req, res) => {
+// In your Express route handler:
+app.post('/auth/callback', async (req, res) => {
   const callbackData: DigiIDCallbackData = req.body; // { address, uri, signature }
-
-  // Retrieve the nonce associated with this login attempt from your session/database
-  const expectedNonce = getNonceForSession(req.sessionID); // Implement this function
-
+  
   const verifyOptions = {
-    // Must match the full URL (including scheme) used during URI generation
-    expectedCallbackUrl: 'https://yourdomain.com/api/digiid/callback', 
-    expectedNonce: expectedNonce, // Crucial for preventing replay attacks
+    expectedCallbackUrl: 'https://your-site.com/auth/callback',
+    expectedNonce: 'your-stored-nonce', // The nonce you generated earlier
   };
 
   try {
     const verificationResult = await verifyDigiIDCallback(callbackData, verifyOptions);
-
-    if (verificationResult.isValid) {
-      console.log(`Successfully verified DigiID login for address: ${verificationResult.address}`);
-      // Proceed with user login/session creation for verificationResult.address
-      // Mark the nonce as used
-      markNonceAsUsed(expectedNonce); // Implement this function
-
-      res.status(200).send({ success: true, address: verificationResult.address });
-    } else {
-      // This case should ideally not be reached as errors are thrown,
-      // but included for completeness.
-      console.warn('Verification returned invalid, but no error was thrown.');
-      res.status(400).send({ success: false, message: 'Verification failed.' });
-    }
-
+    
+    // Verification successful!
+    console.log(`Successfully verified Digi-ID login for address: ${verificationResult.address}`);
+    
+    // Store the verified address in your session/database
+    // Redirect to success page
+    res.redirect('/dashboard');
   } catch (error) {
     if (error instanceof DigiIDError) {
-      // Specific DigiID error (e.g., signature invalid, nonce mismatch, URL mismatch)
-      console.error('DigiID verification failed:', error.message);
-      res.status(400).send({ success: false, message: `Verification failed: ${error.message}` });
+      // Specific Digi-ID error (e.g., signature invalid, nonce mismatch, URL mismatch)
+      console.error('Digi-ID verification failed:', error.message);
+      res.status(400).json({ error: error.message });
     } else {
-      // Unexpected error during verification
-      console.error('An unexpected error occurred during verification:', error);
-      res.status(500).send({ success: false, message: 'Internal server error.' });

+      console.error('Unexpected error:', error);
+      res.status(500).json({ error: 'Internal server error' });

+## Development
 
-## Running Examples
+### Prerequisites
 
-Examples are available in the `examples/` directory. You can run them using `ts-node` via the Node.js loader:
+*   Node.js 18+
+*   npm 9+
 
-```bash
-# Ensure ts-node is installed (npm install -D ts-node)
-node --loader ts-node/esm examples/generate-uri.ts
-node --loader ts-node/esm examples/verify-callback-example.ts
-```
-
-## Dependencies
-
-This library currently uses a specific commit from a fork of `bitcore-message` (`digicontributer/bitcore-message`) for signature verification, matching the original `digiid-js` library. This is an older dependency.
-
-**Future work is planned to replace this with modern, actively maintained cryptographic libraries.**
-
-## Testing
+### Setup
 
-Run tests using Vitest:
+1.  Clone the repository
+2.  Install dependencies: `npm install`
+3.  Run tests: `npm test`
 
-```bash
-npm test
-```
+### Project Structure
 
-Run tests with coverage:
+*   `src/` - Source code
+    *   `digiid.ts` - Core implementation
+    *   `types.ts` - TypeScript type definitions
+*   `test/` - Test files
+*   `examples/` - Usage examples
+*   `dist/` - Built files (generated)
 
-```bash
-npm run coverage
-```
+## License
 
-*(Note: Some unit tests related to mocking the internal signature verification outcome are currently skipped due to challenges with mocking the legacy CJS dependency. These scenarios will be covered by future integration tests.)*
