Customizing Copilot

You can add additional functionality to Copilot in your organization, by installing certain GitHub Apps from GitHub Marketplace.

You can create a file that automatically adds information to all questions you ask Copilot Chat.

Organization owners can create a knowledge base bringing together Markdown documentation across one or more repositories, and then organization members can use that knowledge base as context for Copilot Chat in GitHub.

You can fine-tune Copilot code completion by creating a custom model based on code in your organization's repositories.
