To speed up codespace creation, you can configure your project to prebuild codespaces for specific branches in specific regions.
Who can use this feature?
You create and configure prebuilds in your repository's settings. Repository-level settings for GitHub Codespaces are available for all repositories owned by personal accounts.
For repositories owned by organizations, repository-level settings for GitHub Codespaces are available for organizations on GitHub Team and GitHub Enterprise plans. To access the settings, the organization or its parent enterprise must have added a payment method and set a spending limit for GitHub Codespaces. For more information, see "Choosing who owns and pays for codespaces in your organization" and "GitHub’s plans."
