-4. Use context menu (right-click) for all operations
+1. **Window → Casper SDK → Create Demo Scene**
+2. Play the generated `CasperWalletDemo` scene
+3. Click **Import Keys** to load your Casper Wallet PEM file
+4. Use the UI buttons for all operations

 ## 🎯 Examples
 
-### TestnetDemo Features
+### CasperWalletDemo UI
 
-| Context Menu | Action |
-|--------------|--------|
-| Generate New Account | Create ED25519 key pair |
-| Check Balance | Query CSPR balance |
-| Prepare Test Transfer | Build & sign (no send) |
-| Execute Transfer | Send real CSPR |
-| Export Keys to PEM | For Casper Wallet/Signer |
-| Import Keys from PEM | Load existing keys |
-| Open Testnet Faucet | Get free testnet CSPR |
-| Open Block Explorer | View on cspr.live |
+| Button | Action |
+|--------|--------|
+| Generate Account | Create new ED25519 key pair |
+| Import Keys | Load PEM from Documents/CasperKeys |
+| Refresh Balance | Query CSPR balance |
+| Copy Address | Copy public key to clipboard |
+| Export Keys | Save PEM to Documents/CasperKeys |
+| Open Faucet | Get free testnet CSPR |
+| Send Transaction | Transfer CSPR to recipient |
 
 ### Workflow for Testing
 
-1. **Play** → Account generated
-2. **Export Keys to PEM** → Opens folder
-3. **Import in Casper Wallet** → Upload .pem file
-4. **Faucet** → Request testnet CSPR
-5. **Check Balance** → See 1000 CSPR
-6. **Execute Transfer** → Send to another account
+1. **Casper Wallet → Settings → Download Secret Key** → Save PEM
+2. Copy PEM to `Documents/CasperKeys/`
+3. In Unity: **Window → Casper SDK → Create Demo Scene**
+4. **Play** → Click **Import Keys** → Keys loaded
+5. **Refresh Balance** → See your CSPR
+6. Enter recipient + amount → **Send Transaction**
