What is RubyGems?
RubyGems is the Ruby community's package hosting service, providing a central repository for Ruby libraries and tools. It is maintained and operated by Ruby Central's Open Source Program and the RubyGems team. Ruby developers use RubyGems to discover, install, and publish software packages, known as gems, for their projects. Ruby developers use RubyGems to search for available gems, install them into their development environments, and publish their own gems for others to use. This allows developers to extend the functionality of their Ruby projects by incorporating pre-built components and sharing their own contributions with the community.
