-# Drand Oracle
+# 🎲 Drand Oracle
 
 A Solidity smart contract and updater service for bringing randomness from the [drand network](https://drand.love) on-chain.
 
-## Overview
+## 📄 Contract
 
-This project consists of two main components:
+The `DrandOracle` smart contract serves as an on-chain source of randomness by storing values from the drand network.
 
-1. A Solidity smart contract (`DrandOracle.sol`) that stores randomness values along with necessary metadatas and signatures to verify the randomness off chain.
-2. A Go updater service that fetches new randomness from drand and updates the contract.
+For more information, see the [contract README](contracts/README.md).
 
-## Contract
+## 🔄 Updater
 
-The randomness stored in the contract is verifiable off-chain but not on-chain. This is due to BLS signatures used by Drand network are not yet supported on EVM.
+The updater service fetches new randomness from drand and updates the `DrandOracle` contract with its managed signer and sender EOA addresses.
+
+For more information, see the [updater README](updater/README.md).

+# 📄 Drand Oracle Smart Contract
+
+## 🔎 Overview
+
+The `DrandOracle` smart contract serves as an on-chain source of randomness by storing values from the drand network.
+
+## 📚 Core Contracts
+
+### 🎲 DrandOracle.sol
+
+The main contract responsible for storing and managing randomness from the drand network.
+
+#### 🛠️ Usage
+
+- `getRandomnessFromRound(uint64 _round) external view returns (Random memory)`
+  - Retrieves the complete randomness data for a specific round
+  - Parameters:
+    - `_round`: The round number to query
+  - Returns:
+    - `Random memory`: The Random struct containing the round's data
+- `getRandomnessFromTimestamp(uint64 _timestamp) external view returns (Random memory)`
+  - Retrieves the complete randomness data for a specific timestamp, or the latest timestamp prior to the given timestamp if no exact match is found
+  - Parameters:
+    - `_timestamp`: The timestamp to query
+  - Returns:
+    - `Random memory`: The Random struct containing the timestamp's data
+
+### 🔒 Access Control
+
+The contract implements a simple single-updater access control pattern:
+
+- Only the designated updater address can submit new randomness
+- Updater address is set during contract deployment
+- Updater can be updated by the owner
+
+### ⚠️ Limitations
+
+1. The randomness stored in the contract is verifiable off-chain but not on-chain. This is due to BLS signatures used by Drand network are not yet supported on EVM.
+2. Reliance on trusted updater.
+
+### 🧪 Testing
+
+Run tests with:
+
+```bash
+forge test
+```
+
+### 💻 Run Locally
+
+1. Start local anvil chain
+
+```bash
+anvil
+```
+
+2. Deploy the contract
+
+```bash
+forge build
+make deploy-anvil
+```
