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)
