Feedback

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

If you see any typos or factual errors that you are confident to fix, you can push the fix to <%= link_to 'docrails', 'https://github.com/rails/docrails' %> (Ask the <%= link_to 'Rails core team', 'http://rubyonrails.org/core' %> for push access). If you choose to open a pull request, please do it in <%= link_to 'Rails', 'https://github.com/rails/rails' %> and not in the <%= link_to 'docrails', 'https://github.com/rails/docrails' %> repository. Commits made to docrails are still reviewed, but that happens after you've submitted your contribution. <%= link_to 'docrails', 'https://github.com/rails/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' %>.
