Is the course really free?

A lot of effort and time goes into building such a course and we would really love that you pay at least US$ 15 for the course. Since this is a “Pay if you Like” course, you are under no obligation to pay and hence the course would be free for you.

For those who contribute US$ 15, we shall email them a copy of the book (.pdf) “Introduction to Sinatra” – the course is based on this book.

How do I register and pay the course fees?

  • First, create an account on the site and then pay the fees of US$ 15 by clicking on the PayPal button Paypal
  • After payment of the fees please send us your name to satish [at] rubylearning [dot] org so that we can send you the eBook, which normally takes place within 48 hours.
