+This Cartridge Verfiable Random Function (VRF) is designed to provide cheap, atomic verfiable randomness for fully onchain games.
+
+## Key Features
+
+1. **Atomic Execution**: The VRF request and response are processed within the same transaction, ensuring synchronous and immediate randomness for games.
+
+2. **Efficient Onchain Verification**: Utilizes the Stark curve and Poseidon hash for optimized verification on Starknet.
+
+3. **Fully Onchain**: The entire VRF process occurs onchain, maintaining transparency and verifiability.
+
+4. **Improved Player Experience**: The synchronous nature of the VRF allows for instant resolution of random events in games, enhancing gameplay fluidity.
+
+## How It Works
+
+1. A game calls `request_random(caller, source)` as the first call in their multicall.
+2. A game contract calls `consume_random(source)` from the VRF contract.
+3. The VRF server generates a random value using the VRF algorithm for the provided entropy source.
+4. The Cartridge Paymaster wraps the players multicall with a `submit_random` and `assert_consumed` call.
+5. The random value is immediately available and can be used within the same transaction.
+6. The VRF proof is verified onchain, ensuring the integrity of the random value.
+
+## Benefits for Game Developers
+
+- **Simplicity**: Easy integration with existing Starknet smart contracts.
+- **Performance**: Synchronous randomness generation without waiting for multiple transactions.
+- **Cost-effectiveness**: Potential cost savings through Paymaster integration.
+- **Security**: Cryptographically secure randomness that's fully verifiable onchain.

+
+## Using the VRF Provider
+
+To integrate the Verifiable Random Function (VRF) into your Starknet contract, follow these steps:
+
+1.  Import the VRF Provider interface:
+
+```rust
+use cartridge_vrf::IVrfProviderDispatcher;
+use cartridge_vrf::IVrfProviderDispatcherTrait;
+use cartridge_vrf::Source;
+```
+
+2.  Define the VRF Provider address in your contract:
+
+```rust
+const VRF_PROVIDER_ADDRESS: starknet::ContractAddress = starknet::contract_address_const::<0x123>();
+```
+
+3.  Create a dispatcher for the VRF Provider:
+
+```rust
+let vrf_provider = IVrfProviderDispatcher { contract_address: VRF_PROVIDER_ADDRESS };
+```
+
+4.  To consume random values, use the following pattern in your contract functions:
+
+```rust
+fn roll_dice(ref self: ContractState) {
+    // Your game logic here...
+
+    // Consume random value
+    let random_value = vrf_provider.consume_random(Source::Salt('SALT'));
+
+    // Use the random value in your game logic
+    // ...
+}
+```
+
+5.  You can use either `Source::Nonce(ContractAddress)` or `Source::Salt(felt252)` as the source for randomness:
+
+    -   `Source::Nonce(ContractAddress)`: Uses the contract's address and an internal nonce for randomness.
+    -   `Source::Salt(felt252)`: Uses a provided salt value for randomness.
+
+## Executing VRF transactions
+
+In order to execute a transaction that includes a `consume_random` call, you need to include a `request_random` transaction as the first transaction in the multicall. The `request_random` call allows our server to efficiently parse transactions that include a `consume_random` call internally.
+
+```js
+const call = await account.execute([
+  // Prefix the multicall with the 
+  {
+    contractAddress: VRF_PROVIDER_ADDRESS,
+    entrypoint: 'request_random',
+    calldata: CallData.compile({
+      caller: GAME_CONTRACT,
+      // User provided Salt
+      source: [1, SALT],
+    }),
+  },
+  {
+    contractAddress: GAME_CONTRACT,
+    entrypoint: 'roll_dice',
+    ...
+  },
+]);
+```
+
+**Ensure that you call `consume_random` with the same `Source` as used in `request_random`.**
+
+By following these steps, you can integrate the VRF Provider into your Starknet contract and generate verifiable random numbers for your onchain game or application.
