+# Copilot Setup Steps - Implementation Guide
+
+This document explains the automated copilot setup implementation for the Onchain Test Kit project.
+
+## Overview
+
+The "Copilot Setup Steps" feature provides automated workflows and scripts that ensure development environments are properly configured according to the guidelines in `.github/copilot-instructions.md`.
+
+## Components Implemented
+
+### 1. GitHub Actions Workflows (`.github/workflows/`)
+
+#### `copilot-setup.yml`
+- **Purpose**: Main CI/CD workflow that runs on push/PR
+- **Triggers**: Push to main/develop/copilot branches, PRs to main/develop
+- **Features**: 
+  - Runs all essential setup commands in correct order
+  - Handles known broken wallet preparations gracefully
+  - Includes validation job
+  - Uses Node.js 18 with npm caching
+
+#### `development.yml` 
+- **Purpose**: Development-focused workflow for code quality
+- **Features**:
+  - Separate jobs for linting, building, testing
+  - Wallet preparation testing
+  - Test artifact upload on failure
+  - Dependency separation for faster execution
+
+#### `manual-setup-test.yml`
+- **Purpose**: Manual testing workflow with configurable options
+- **Features**:
+  - Workflow dispatch triggers
+  - Options to test wallet preparation and run full validation
+  - Detailed summary reporting
+
+### 2. Setup Scripts (`scripts/`)
+
+#### `quick-setup.sh`
+- **Purpose**: Automated execution of essential setup commands
+- **Features**:
+  - Follows exact order from copilot-instructions.md
+  - Colored output for better visibility
+  - Graceful handling of known issues
+  - Error handling with `set -e`
+
+#### `validate-setup.sh`
+- **Purpose**: Comprehensive environment validation
+- **Features**:
+  - Node.js version checking (>=14.0.0 requirement)
+  - Step-by-step validation with detailed output
+  - Known issue reporting for broken wallet preparations
+  - Success/warning/error status indicators
+
+### 3. Package.json Integration
+
+Added convenient npm commands:
+```json
+{
+  "copilot:setup": "./scripts/quick-setup.sh",
+  "copilot:validate": "./scripts/validate-setup.sh", 
+  "copilot:full-setup": "npm run copilot:setup && npm run copilot:validate"
+}
+```
+
+### 4. Documentation Updates
+
+#### README.md
+- Added "Copilot Setup Steps" section
+- Quick reference for setup commands
+- Links to instruction files for AI agents
+- Integration with existing documentation
+
+#### GitHub Issue Template (`.github/ISSUE_TEMPLATE/setup.yml`)
+- Structured template for setup issues
+- Checkboxes for common setup steps
+- Environment and version information collection
+- Links to relevant documentation
+
+## Essential Commands Automated
+
+Based on `.github/copilot-instructions.md`, these commands are automated:
+
+1. `npm install` - Install dependencies (required first)
+2. `npm run build` - Build project (required before testing)
+3. `npm run lint` - Run linter (fix issues before committing)
+4. `npm run format` - Format code (may show extension file warnings)
+5. `npm run test` - Run tests
+6. `npm run prepare-metamask` - Prepare MetaMask (works correctly)
+7. `npm run prepare-coinbase` - Prepare Coinbase (known broken, gracefully handled)
+8. `npm run prepare-phantom` - Prepare Phantom (known broken, gracefully handled)
+
+## Usage Examples
+
+### For Developers
+```bash
+# Quick setup
+npm run copilot:setup
+
+# Full setup with validation
+npm run copilot:full-setup
+
+# Validation only
+npm run copilot:validate
+```
+
+### For CI/CD
+The workflows automatically trigger on:
+- Push to main, develop, or copilot/** branches
+- Pull requests to main or develop branches
+- Manual dispatch for testing
+
+### For AI Coding Agents
+The setup follows the instructions in:
+- `.github/copilot-instructions.md` - Main instructions
+- `.github/instructions/*.instructions.md` - Specialized guidance
+- `AGENTS.md`, `CLAUDE.md`, `GEMINI.md` - Agent-specific instructions
+
+## Error Handling
+
+### Known Issues Handled
+1. **Coinbase/Phantom preparation fails**: Gracefully continues with warnings
+2. **Format command warnings**: Expected for extension files, safely ignored
+3. **Node.js version**: Validates >=14.0.0 requirement
+4. **Missing dependencies**: Clear error messages with resolution steps
+
+### Validation Features
+- Pre-flight checks for Node.js version
+- Step-by-step validation with clear success/failure indicators
+- Comprehensive error reporting
+- Links to troubleshooting resources
+
+## Integration with Existing Infrastructure
+
+### Builds on Existing Foundation
+- Leverages existing npm scripts
+- Uses established biome linting/formatting setup
+- Integrates with Playwright testing infrastructure
+- Respects existing wallet preparation scripts
+
+### Maintains Compatibility
+- No breaking changes to existing APIs
+- Backward compatible with existing development workflows
+- Additive approach - enhances rather than replaces existing tools
+
+## Future Enhancements
+
+Potential improvements:
+1. **Wallet Preparation Fix**: Address broken Coinbase/Phantom downloads
+2. **Performance Optimization**: Parallel execution where safe
+3. **Environment Detection**: Adaptive behavior for different environments
+4. **Setup Analytics**: Track setup success rates and common issues
+5. **Interactive Setup**: Guide users through setup with prompts
+
+## Success Criteria
+
+✅ **Implemented Successfully:**
+- Automated setup workflows in GitHub Actions
+- Local setup scripts with proper error handling
+- Integration with package.json for easy access
+- Documentation updates in README
+- Issue template for setup problems
+- Maintains all existing functionality
+- Follows exact command sequence from instructions
+- Handles known issues gracefully
+
+The implementation provides a robust foundation for automated onchain test kit setup while maintaining flexibility for different use cases and environments.
