It's a free workshop on Sat March 22nd, run by volunteers. It's aimed at beginners, so will go from scratch to building an application together using Ruby on Rails. Girls and women of any age and experience welcome.
Sounds like a great way to dip your toes in the water if you've always been curious about building a web app/learning to code!
