Because of being invited to take part in a Rails Girls event, I created two presentations. Both of them are intended to be used as short introductions (to Ruby and Git, respectively).
Take a look if you’d like to use them to train other beginners, possibly at an another Rails Girls event.

Introduction to Ruby
It tries to cover:
- Variables;
- simple calculations;
- conditions;
- functions;
- collections;
- symbols;
- classes.
Introduction to Git
It goes through the basic workflow:
- Cloning the repository (git clone).
- Working on files.
- What’s the situation? (git status)
- What exactly have I done? (git diff)
- I want to share these changes (git add)
- Double-checking (git diff --cached)
- Making a commit (git commit)
- Sharing your changes (git push)
