Hello,

I'm writing a tutorial for beginners, primarily aimed at Teachers and Students.

I've written the following tutorial.

http://www.oriontransfer.co.nz/education/learn-ruby/lesson-0/index

Any feedback would be really really helpful. Thanks to anyone who takes a look.

Any suggestions or feedback would be fantastic - what should I add or remove, what was not clear / etc.

Kind regards,
Samuel

Hello,

I think there is a small error in the last example. It's written:
             # Do you wear a watch? Ruby can help you out!
             puts "The time is: \#{Time.now.to_s}"

I think it should say:

             puts "The time is: #{Time.now.to_s}"

I haven't read the tutorial, but this can be written as:

puts "The time is: #{Time.now}"

since string interpolation calls to_s for you.

Jesus.
