-## Development Setup
+## CI Status
 
-### Prerequisites
+[![Smart Contract CI](https://github.com/BrainTease/Brain-Storm/actions/workflows/contract.yml/badge.svg)](https://github.com/BrainTease/Brain-Storm/actions/workflows/contract.yml)
 
-- Rust stable (latest)
-- Soroban SDK v20.0.0+
-- Stellar CLI v20.0.0+
+The CI workflow runs on every push and PR, ensuring code quality and functionality.
 
-### Installation
-
-```bash
-# Install Rust
-curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

-# Install Soroban CLI
-cargo install soroban-cli
-
-# Install wasm-opt (optional, for optimization)
-# macOS
-brew install binaryen
-
-# Ubuntu
-sudo apt-get install binaryen
-# Build all contracts
-cargo build --target wasm32-unknown-unknown --release
-
-# Build specific contract
-cd stellar-contract
-cargo build --target wasm32-unknown-unknown --release
-# Deploy contract

+### Workflow Steps
+1. **Lint** - `cargo fmt` and `cargo clippy`
+2. **Test** - `cargo test` with coverage
+3. **Build** - WASM compilation
+4. **Coverage** - Code coverage reporting
