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', '' %>
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', '' %> 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', '' %>.
<p>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', '' %>.
