Description

@GitHub Copilot - Welcome @BanterBoy, I’m your Copilot and I’m here to help you get things done faster. I can identify issues, explain and even improve code.

You can ask generic questions, but what I’m really good at is helping you with your code. For example:

Generate unit tests for my code Explain the selected code Propose a fix for the bugs in my code If you want to learn more about my capabilities and limitations, check out the Copilot documentation.

I’m powered by AI, so surprises and mistakes are possible. Make sure to verify any generated code or suggestions, and share feedback so that we can learn and improve.
