## Description

The GitHub Repository Size Chrome extension enhances your GitHub experience by displaying the size of repositories directly in their summary band, next to contributors and license information. Utilizing the GitHub public API, it provides quick size insights for both public and private repositories.

For private repositories, the extension prompts for a Personal Access Token with the 'repo' scope to fetch size data securely. While the size details are sourced from GitHub's API, note that they may be approximate due to how GitHub internally stores repository data. This tool is ideal for developers seeking immediate visibility into repository sizes without navigating away from GitHub.
