To quote the statement of the Rails Girls mission:
Our aim is to give tools and a community for women to understand technology and to build their ideas. We do this by providing a great experience on building things and by making technology more approachable. Learn sketching, prototyping, basic programming and get introduced to the world of technology. Rails Girls was born in Finland, but is nowadays a global, non-profit volunteer community.
Founded by Linda Liukas and Karri Saarinen. The first event, held in Helsinki in November 2010, got over 100 interested girls signed-up for the workshop.
Since then the free events have expanded to Shanghai, Singapore, Tallinn, Berlin, Krakow and many more attracting thousands of girls to the world of web building.
In May 2014 I got the opportunity to mentor the event. It was a delightful experience and to see all those girls interested in the line of work us geeks do, it was really mesmerizing. I enjoyed doing it and would gladly do it again (not only for the free T-Shirt that was provided to all the mentors).
