GitHub Copilot supports custom instructions that teach it your team's coding standards, preferences, and conventions.

How to Set Custom Instructions

• Create a .github/copilot-instructions.md file in your repo
• Add your team's coding standards and preferences
• Copilot will follow these instructions in that repo automatically

Example Instructions

- Use TypeScript strict mode
- Prefer functional components in React
- Always add error handling to async functions
- Use camelCase for variables, PascalCase for components
- Add JSDoc comments to all exported functions
