          The closest thing I can think of is adding a default task and using it to invoke the help task. You'd get this message when calling $my_command with no arguments



          require 'thor'
          class MyCLI < Thor
          desc "hello NAME", "say hello to NAME"
          def hello(name)
          puts "Hello #{name}"
          end
          desc "greeting", "this is just a greeting"
          def greeting
          puts "Welcome to MyCLI"
          invoke :help
          end
          default_task :greeting
          end

          MyCLI.start(ARGV)

          # $my_command
          # output:

          # Welcome to MyCLI
          # Commands:
          # test.rb greeting # this is just a greeting
          # test.rb hello NAME # say hello to NAME
          # test.rb help [COMMAND] # Describe available commands or one spec...
