# 🤖 Awesome GitHub Copilot Customizations

Enhance your GitHub Copilot experience with community-contributed instructions, prompts, and configurations. Get consistent AI assistance that follows your team's coding standards and project requirements.

## 🎯 GitHub Copilot Customization Features

GitHub Copilot provides three main ways to customize AI responses and tailor assistance to your specific workflows, team guidelines, and project requirements:

| **🔧 Custom Instructions** | **📝 Reusable Prompts** | **🧩 Custom Chat Modes** |
| --- | --- | --- |
| Define common guidelines for tasks like code generation, reviews, and commit messages. Describe *how* tasks should be performed<br><br>**Benefits:**<br>• Automatic inclusion in every chat request<br>• Repository-wide consistency<br>• Multiple implementation options | Create reusable, standalone prompts for specific tasks. Describe *what* should be done with optional task-specific guidelines<br><br>**Benefits:**<br>• Eliminate repetitive prompt writing<br>• Shareable across teams<br>• Support for variables and dependencies | Define chat behavior, available tools, and codebase interaction patterns within specific boundaries for each request<br><br>**Benefits:**<br>• Context-aware assistance<br>• Tool configuration<br>• Role-specific workflows |

> **💡 Pro Tip:** Custom instructions only affect Copilot Chat (not inline code completions). You can combine all three customization types - use custom instructions for general guidelines, prompt files for specific tasks, and chat modes to control the interaction context.
