def help(topic = nil)
  if topic.nil?

    puts <<EOF

Available commands:

`[resource]` - run resource on target machine
`help resources` - show all available resources that can be used as commands
`help [resource]` - information about a specific resource
`help matchers` - show information about common matchers
`exit` - exit the InSpec shell

You can use resources in this environment to test the target machine. For example:

command('uname -a').stdout
file('/proc/cpuinfo').content => "value"

#{print_target_info}
EOF
  elsif topic == 'resources'
    resources.sort.each do |resource|
      puts " - #{resource}"
    end
  elsif topic == 'matchers'
    print_matchers_help
  elsif !Inspec::Resource.registry[topic].nil?
    topic_info = Inspec::Resource.registry[topic]
    info = "#{mark 'Name:'} #{topic}\n\n"
    unless topic_info.desc.nil?
      info += "#{mark 'Description:'}\n\n"
      info += "#{topic_info.desc}\n\n"
    end

    unless topic_info.example.nil?
      info += "#{mark 'Example:'}\n"
      info += "#{print_example(topic_info.example)}\n\n"
    end

    info += "#{mark 'Web Reference:'}\n\n"
    info += "https://www.inspec.io/docs/reference/resources/#{topic}\n\n"
    puts info
  else
    puts "The resource #{topic} does not exist. For a list of valid resources, type: help resources"
  end
end
