You're encouraged to help improve the quality of this guide.

If you see any typos or factual errors you are confident to patch, please clone <%= link_to 'docrails', 'https://github.com/lifo/docrails' %> and push the change yourself. That branch of Rails has public write access. Commits are still reviewed, but that happens after you've submitted your contribution. <%= link_to 'docrails', 'https://github.com/lifo/docrails' %> is cross-merged with master periodically.

You may also find incomplete content, or stuff that is not up to date. Please do add any missing documentation for master. Check the <%= link_to 'Ruby on Rails Guides Guidelines', 'ruby_on_rails_guides_guidelines.html' %> for style and conventions.

If for whatever reason you spot something to fix but cannot patch it yourself, please <%= link_to 'open an issue', 'https://github.com/rails/rails/issues' %>.

And last but not least, any kind of discussion regarding Ruby on Rails documentation is very welcome in the <%= link_to 'rubyonrails-docs mailing list', 'http://groups.google.com/group/rubyonrails-docs' %>.
