Documentation is a Rails engine which provides a complete system for managing a set of hierarchical documentation. Once installed in an application, you'll have a complete user interface for viewing as well as editing a set of markdown pages.
To get started, you need to add Documentation to your Gemfile and run bundle.
gem 'documentation', '~> 1.0.0'
Next, you'll need to run the setup generator which will add a route to your config/routes.rb file for the Documentation interface.
bundle exec rails generate documentation:setup
You now need to populate your database schema and load the initial documentation pages.
bundle exec rake db:migrate documentation:install_guides
Once this is done, you can go ahead and start up your Rails application and browse to /docs to view your documentation system.
