Install a Plugin

For most users, the Awesome Copilot marketplace is already registered in the Copilot CLI/VS Code, so you can install a plugin directly:

copilot plugin install <plugin-name>@awesome-copilot

If you are using an older Copilot CLI version or a custom setup and see an error that the marketplace is unknown, register it once and then install:

copilot plugin marketplace add github/awesome-copilot
copilot plugin install <plugin-name>@awesome-copilot
