+## About this presentation
+
+`FRIEND`: Hey Simone, I want to start learning Rails.
+
+`ME`: Really?
+
+`FRIEND`: You know, I have been working in PHP and Symfony for a while and now I want to try something new.
+
+`ME`: That's cool.
+
+`FRIEND`: Could you help me studying Rails?
+
+`ME`: Sure. But if you really want to learn Rails, you need to start from Ruby.
+
+`FRIEND`: I worked with PHP and several other languages. Is Ruby really that difficult?
+
+`ME`: Learning the Ruby syntax is not that difficult. Thinking like a Rubyist is the real challenge. If you really want to appreciate Ruby, you must understand the Ruby ecosystem and the philosophy behind the language.
+
+`FRIEND`: Ok. Could you teach me that?
+
+`ME`: I can start giving you some directions, then you'll have to start working on it.
+
+`ME`: I'm going to prepare a brief introduction to Ruby. I'll try to extract the most important features of the language, keeping an eye on Rails since that is your ultimate goal.
+
+`FRIEND`: Cool. How long it will take.
+
+`ME`: Let's schedule one full day. I'll show you the presentation and we'll start digging into Ruby. At the end, we'll try to summarize everything by giving a look at Rack and creating a small MVC application using the awesome Sinatra framework. It is not Rails, but it's definitely a good starting point. We can't concentrate too much concepts into a single session.
+
+`FRIEND`: I agree.
+
+`FRIEND`: See you on Saturday, I can't wait to start playing with Ruby.
+
+
+This is *that* presentation. **Enjoy Ruby!**
