These files comprise the WP-CLI handbook (make.wordpress.org/cli/handbook) and WP-CLI commands directory (developer.wordpress.org/cli/commands).

The documentation is located in GitHub to enable a pull request-based editing workflow. Long-form documentation (e.g. "Commands cookbook") can be edited directly. Internal API docs and command pages are generated dynamically from the WP-CLI codebase using the wp handbook series of commands.

All documentation is imported automatically into WordPress.org in a two step process:

1. WordPress reads commands-manifest.json or handbook-manifest.json to understand all pages that need to be created.
2. Each WordPress page has a markdown_source attribute specifying a Markdown file to be fetched, converted to HTML, and saved in the database.

For make.wordpress.org/cli, the import process is a WordPress plugin running a WP Cron job every 15 minutes. For developer.wordpress.org/cli, this is a class in the devhub theme running a WP Cron job every 12 hours.
