+# PropChain Development Environment Setup
+
+This guide will help you set up a complete development environment for PropChain smart contracts.
+
+## Quick Start
+
+```bash
+# Clone and setup
+git clone https://github.com/MettaChain/PropChain-contract.git
+cd PropChain-contract
+./scripts/setup.sh
+
+# Start local development environment
+docker-compose up -d
+
+# Run tests
+./scripts/test.sh
+
+# Build contracts
+./scripts/build.sh --release
+```
+
+## Prerequisites
+
+- **Rust** 1.70+ with stable toolchain
+- **Docker** and Docker Compose
+- **Node.js** 16+ (for frontend development)
+- **Git**
+
+## Manual Setup
+
+### 1. Install Rust and Tools
+
+```bash
+# Install Rust
+curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh
+source ~/.cargo/env
+
+# Install cargo-contract
+cargo install cargo-contract --locked
+
+# Add WASM target
+rustup target add wasm32-unknown-unknown
+```
+
+### 2. Setup Pre-commit Hooks
+
+```bash
+./scripts/setup-pre-commit.sh
+```
+
+### 3. Start Local Development
+
+```bash
+# Start blockchain node
+./scripts/local-node.sh start
+
+# Or use Docker Compose for full stack
+docker-compose up -d
+```
+
+## Development Workflow
+
+### Building Contracts
+
+```bash
+# Debug build
+./scripts/build.sh
+
+# Release build
+./scripts/build.sh --release
+
+# Clean build
+./scripts/build.sh --clean
+```
+
+### Running Tests
+
+```bash
+# All tests
+./scripts/test.sh
+
+# Unit tests only
+./scripts/test.sh --no-integration
+
+# With coverage
+./scripts/test.sh --coverage
+
+# E2E tests
+./scripts/e2e-test.sh
+```
+
+### Code Quality
+
+```bash
+# Format code
+cargo fmt
+
+# Run linting
+cargo clippy
+
+# Pre-commit checks
+pre-commit run --all-files
+```
+
+### Deployment
+
+```bash
+# Local deployment
+./scripts/deploy.sh --network local
+
+# Testnet deployment
+./scripts/deploy.sh --network westend
+
+# Mainnet deployment
+./scripts/deploy.sh --network polkadot
+```

+
+## Environment Configuration
+
+### Local Development (.env.local)
+
+```env
+NETWORK=local
+NODE_URL=ws://localhost:9944
+SURI=//Alice
+```
+
+### Testnet (.env.westend)
+
+```env
+NETWORK=westend
+NODE_URL=wss://westend-rpc.polkadot.io
+SURI=your-testnet-mnemonic
+```
+
+### Mainnet (.env.polkadot)
+
+```env
+NETWORK=polkadot
+NODE_URL=wss://rpc.polkadot.io
+SURI=your-mainnet-mnemonic
+```
+
+## Common Issues and Solutions
+
+### Rust Installation Issues
+
+```bash
+# If Rust is not found
+source ~/.cargo/env
+
+# Update Rust toolchain
+rustup update stable
+```
+
+### Contract Build Failures
+
+```bash
+# Clean build artifacts
+cargo clean
+rm -rf target/
+
+# Rebuild
+./scripts/build.sh --clean
+```
+
+### Node Connection Issues
+
+```bash
+# Check if node is running
+curl http://localhost:9933/health
+
+# Restart local node
+./scripts/local-node.sh restart
+```
+
+### Pre-commit Hook Issues
+
+```bash
+# Reinstall hooks
+./scripts/setup-pre-commit.sh --test-only
+
+# Run hooks manually
+pre-commit run --all-files
+```
+
+## IDE Configuration
+
+### VS Code
+
+Install these extensions:
+- Rust Analyzer
+- TOML Language Support
+- Docker
+- GitLens
+
+### Workspace Settings (.vscode/settings.json)
+
+```json
+{
+    "rust-analyzer.checkOnSave.command": "clippy",
+    "rust-analyzer.cargo.loadOutDirsFromCheck": true,
+    "editor.formatOnSave": true,
+    "files.trimTrailingWhitespace": true
+}
+```
