CargoWiki

cargo_wiki allows you to install a wiki in a Rails 3 application.

Add cargo_wiki to your Gemfile:

gem 'cargo_wiki'

cargo_wiki uses compass, and you must add compass support in the assets group of your Gemfile:

group :assets do
  gem 'compass-rails'
end

Then run:

bundle install

You also need to update your database:

rails generate cargo_wiki:install
rake db:migrate

Finally mount the engine in routes.rb:

mount CargoWiki::Engine => "/wiki"

You are free to mount the wiki to whatever url you want.
