an implementation of the Ruby language on the JVM\n\nMaster: [![JRuby CI](https://github.com/jruby/jruby/actions/workflows/ci.yml/badge.svg)](https://github.com/jruby/jruby/actions/workflows/ci.yml), [![JRuby CI (Windows)](https://github.com/jruby/jruby/actions/workflows/ci-windows.yml/badge.svg)](https://github.com/jruby/jruby/actions/workflows/ci-windows.yml)\n9.3 branch: [![JRuby CI](https://github.com/jruby/jruby/actions/workflows/ci.yml/badge.svg?branch=jruby-9.3)](https://github.com/jruby/jruby/actions/workflows/ci.yml), [![JRuby CI (Windows)](https://github.com/jruby/jruby/actions/workflows/ci-windows.yml/badge.svg?branch=jruby-9.3)](https://github.com/jruby/jruby/actions/workflows/ci-windows.yml)\n\n## About\n\nJRuby is an implementation of the [Ruby language](http://www.ruby-lang.org)\nusing the JVM.\n\nIt aims to be a complete, correct and fast implementation of Ruby, at the same\ntime as providing powerful new features such as concurrency without a\n[global-interpreter-lock](http://en.wikipedia.org/wiki/Global_Interpreter_Lock),\ntrue parallelism, and tight integration to the Java language to allow you to\nuse Java classes in your Ruby program and to allow JRuby to be embedded into a\nJava application.\n\nYou can use JRuby simply as a faster version of Ruby, you can use it to run Ruby\non the JVM and access powerful JVM libraries such as highly tuned concurrency\nprimitives, you can use it to embed Ruby as a scripting language in your Java\nprogram, or many other possibilities.\n\nWe're a welcoming community - you can talk to us on [#jruby on Libera](https://libera.chat/).\nThere are core team members in the EU and US time zones.\n\nVisit the [JRuby website](https://www.jruby.org/) and the [JRuby wiki](https://github.com/jruby/jruby/wiki)\nfor more information.\n\n## Getting JRuby\n\nTo run JRuby you will need a JRE (the Java VM runtime environment) version 8 or higher.\n\nYour operating system may provide a JRE and JRuby in a package manager, but you may find that this\nversion is very old.\n\nAn alternative is to use one of the [Ruby version managers](https://www.ruby-lang.org/en/documentation/installation/#managers).\n\nFor [`rbenv`](https://github.com/sstephenson/rbenv) you will need the\n[`ruby-build`](https://github.com/sstephenson/ruby-build) plugin. You may find that your system\npackage manager can provide these. To see which versions of JRuby are available you should run:\n\n```\n$ rbenv install jruby\n```\n\nNote: if you do not regularly git update rbenv this list of versions may be out of date.\n\nWe recommend always selecting the latest version of JRuby from the list. \nYou can install that particular version (9.2.13.0 is just for illustration):\n\n\n```\n$ rbenv install jruby-9.2.13.0\n```\n\nFor [`rvm`](https://rvm.io) you can simply do:\n\n```\n$ rvm install jruby\n```\n\nUsing [`Homebrew`](https://brew.sh/) works too:\n\n```\n$ brew install jruby\n```\n\nYou can also [download packages from the JRuby website](https://www.jruby.org/download) that\nyou can unpack and run in place.\n\n## Building JRuby\n\nSee [BUILDING](BUILDING.md) for information about prerequisites, how to compile JRuby from source\nand how to test it.\n\n## Authors\n\nStefan Matthias Aust, Anders Bengtsson, Geert Bevin, Ola Bini,\n Piergiuliano Bossi, Johannes Brodwall, Rocky Burt, Paul Butcher,\n Benoit Cerrina, Wyss Clemens, David Corbin, Benoit Daloze, Thomas E Enebo,\n Robert Feldt, Chad Fowler, Russ Freeman, Joey Gibson, Kiel Hodges,\n Xandy Johnson, Kelvin Liu, Kevin Menard, Alan Moore, Akinori Musha,\n Charles Nutter, Takashi Okamoto, Jan Arne Petersen, Tobias Reif, David Saff,\n Subramanya Sastry, Chris Seaton, Nick Sieger, Ed Sinjiashvili, Vladimir Sizikov,\n Daiki Ueno, Matthias Veit, Jason Voegele, Sergey Yevtushenko, Robert Yokota,\n   and many gracious contributors from the community.\n\nJRuby uses code generously shared by the creator of the Ruby language,\nYukihiro Matsumoto \u003cmatz@netlab.co.jp\u003e.\n\nProject Contact: Thomas E Enebo \u003ctom.enebo@gmail.com\u003e\n\n## License\n\nJRuby is licensed under a tri EPL/GPL/LGPL license.
