+
+## Getting Started
+
+### 1. Installation
+
+```bash
+# Install dependencies
+npm install @openfort/openfort-js @openfort/openfort-node
+npm install ethers viem
+```
+
+### 2. Configuration
+
+```typescript
+// Initialize Openfort with client and server configurations
+// Client side
+const openfortClient = new Openfort({
+  baseConfiguration: {
+    publishableKey: "YOUR_OPENFORT_PUBLISHABLE_KEY",
+  },
+  shieldConfiguration: {
+    shieldPublishableKey: "YOUR_SHIELD_PUBLISHABLE_KEY",
+  },
+});
+
+// Server side
+const openfortServer = new Openfort("YOUR_SECRET_KEY");
+```
+
+### 3. Basic Implementation
+
+```typescript
+// Authentication
+const authResponse = await openfort.logInWithEmailPassword({
+  email: "[email protected]",
+  password: "password123"
+});
+
+// Initialize Provider
+const provider = await openfort.getProvider();
+await provider.request({ 
+  method: 'wallet_switchEthereumChain',
+  params: [{ chainId: `0x${avalancheChain.id.toString(16)}` }]
+});
+
+// Create a gas sponsorship policy (server-side)
+const policy = await openfortServer.policies.create({
+  chainId: 43114, // Avalanche C-Chain
+  name: "Gas Sponsorship Policy",
+  strategy: {
+    sponsorSchema: "pay_for_user"
+  }
+});
+
+// Create transaction intent with sponsorship (server-side)
+const transactionIntent = await openfortServer.transactionIntents.create({
+  player: "PLAYER_ID",
+  chainId: 43114,
+  optimistic: true,
+  policy: policy.id,
+  interactions: [{
+    contract: "CONTRACT_ADDRESS",
+    functionName: "transfer",
+    functionArgs: [recipientAddress, amount]
+  }]
+});
+
+// Sign and send the sponsored transaction (client-side)
+const response = await openfortClient.sendSignatureTransactionIntentRequest(
+  transactionIntent.id,
+  transactionIntent.nextAction.payload.userOperationHash
+);
+```
