+# Migrating to Base Apps SDK
+
+Base has evolved the "Mini Apps" ecosystem into the broader **Base Apps**. This transition involves a few breaking changes in the SDK and documentation structure.
+
+## Quick Checklist
+- [ ] Rename `useMiniKit` to `useBaseApp`.
+- [ ] Update imports from `@coinbase/minikit` to the latest version.
+- [ ] Review Farcaster manifest requirements (now optional for standard web apps).
+
+## Code Changes
+
+### Hook Update
+```typescript
+// Old
+import { useMiniKit } from "@coinbase/minikit";
+
+// New
+import { useBaseApp } from "@coinbase/minikit";

+
+# Implement Spend Permissions
+
+Spend Permissions allow smart wallets to grant specific allowances to a spender (your app's backend) for a set period. This enables seamless experiences like subscriptions, automatic trading, or gasless payments.
+
+## How it works
+
+1. **Request Permission:** The user signs a typed data structure defining the `allowance`, `period`, and `spender`.
+2. **Onchain Approval:** The signature is submitted to the `SpendPermissionManager` contract.
+3. **Execution:** The authorized spender calls `spend()` to transfer assets within the allowed limit.
+
+## Implementation Steps
+
+### 1. Build the Permission
+```typescript
+const permission = {
+  account: userAddress,
+  spender: "0xYourBackendAddress",
+  token: "0xEeeeeEeeeEeEeeEeEeEeeEEEeeeeEeeeeeeeEEeE", // Native ETH
+  allowance: parseEther("0.1"),
+  period: 2592000, // 30 days
+  start: Math.floor(Date.now() / 1000),
+  end: Math.floor(Date.now() / 1000) + (2592000 * 12), // 1 year
+  salt: BigInt(0),
+  extraData: "0x",
+};
