# Short-Description: Private, Fast, Reliable DevOps Platform
# Description:       A lightweight, self-hosted Git service that provides a
#                    web-based interface for managing Git repositories. It is
#                    designed to be easy to install and configure, making it
#                    accessible for individuals and organizations looking to
#                    host their own version control system. Gitea offers
#                    features such as issue tracking, pull requests, code
#                    reviews, and a built-in wiki, all while maintaining a
#                    user-friendly experience. Its open-source nature allows
#                    for customization and community contributions, making it
#                    a popular choice for developers seeking an alternative to
#                    larger platforms like GitHub or GitLab.
