What you need for this book

In order to write plugins for Redmine, a working Ruby/Rails environment should be available, as well as a copy of Redmine.

Setting up Ruby is platform dependent, but we can get started relatively quickly. For instructions for Windows, visit http://rubyinstaller.org/. For OSX or Linux, visit either http://rvm.io/ or https://github.com/sstephenson/rbenv.

The Redmine source code can be downloaded at http://www.redmine.org or from GitHub at https://github.com/redmine/redmine.

If you've never set up Redmine yourself, a comprehensive guide is available at http://www.redmine.org/projects/redmine/wiki/RedmineInstall.
