+# Bitcoin Yield Aggregator
+
+A secure and efficient DeFi yield strategy management system built on Bitcoin using Clarity smart contracts.
+
+## Overview
+
+The Bitcoin Yield Aggregator enables users to:
+
+- Deposit tokens into various yield-generating protocols
+- Manage protocol allocations dynamically
+- Earn and claim rewards based on protocol performance
+- Benefit from automated strategy rebalancing
+
+## Key Features
+
+- **Protocol Management**: Add, update, and manage yield-generating protocols
+- **Token Integration**: SIP-010 compliant token support with whitelisting
+- **Secure Deposits**: Rate-limited deposits with comprehensive validation
+- **Dynamic Rewards**: APY-based reward calculation and distribution
+- **Emergency Controls**: Emergency shutdown mechanism for risk management
+- **Rate Limiting**: Protection against abuse through operation rate limiting
+
+## Security Features
+
+- Protocol whitelisting
+- Emergency shutdown mechanism
+- Rate limiting
+- Comprehensive input validation
+- Balance verification
+- SIP-010 compliance checks
+
+## Getting Started
+
+### Prerequisites
+
+- Stacks blockchain environment
+- SIP-010 compliant tokens
+- Clarity smart contract knowledge
+
+### Contract Deployment
+
+1. Deploy the contract to the Stacks blockchain
+2. Set initial parameters (platform fee, deposit limits)
+3. Whitelist supported tokens
+4. Add yield-generating protocols
+
+### Usage
+
+```clarity
+;; Deposit tokens
+(contract-call? .yield-aggregator deposit token-trait amount)
+
+;; Withdraw tokens
+(contract-call? .yield-aggregator withdraw token-trait amount)
+
+;; Claim rewards
+(contract-call? .yield-aggregator claim-rewards token-trait)
+```
+
+## Architecture
+
+The contract is structured into several key components:
+
+- Protocol Management
+- Token Management
+- Deposit/Withdrawal Handling
+- Reward Distribution
+- Administrative Controls
+

+# Technical Specification
+
+## Contract Overview
+
+The Bitcoin Yield Aggregator is a DeFi protocol for managing yield-generating strategies on Bitcoin using Clarity smart contracts.
+
+## Core Components
+
+### State Management
+
+```clarity
+;; TVL and Platform Parameters
+(define-data-var total-tvl uint u0)
+(define-data-var platform-fee-rate uint u100)
+(define-data-var min-deposit uint u100000)
+(define-data-var max-deposit uint u1000000000)
+(define-data-var emergency-shutdown bool false)
+```
+
+### Data Structures
+
+```clarity
+;; User Deposits
+(define-map user-deposits
+    { user: principal }
+    { amount: uint, last-deposit-block: uint })
+
+;; Protocol Configuration
+(define-map protocols
+    { protocol-id: uint }
+    { name: (string-ascii 64), active: bool, apy: uint })
+```
+
+## Key Functions
+
+### Deposit Management
+
