What you need

• Make sure Git is installed and is available from the command line ( git --version should not produce an error). Install Git if you do not already have it.

• A good text editor of your choice, such as Atom, SublimeText, or Visual Studio Code.

How to get started

• Although you have this README.md file on your computer, it's easier to read it on GitHub with formatting. We therefore recommend you keep a web browser tab open with the exercise tasks.
• Start by opening exercise 1.
• Remember to ask an instructor if you're stuck.

❗ Do not use a GUI client. Use the terminal/CLI only. You should not copy and paste content. Type it out manually. Remember to follow all the steps in the tutorial.

Exercises

This repository contains a set of exercises organized in folders. Each folder contains a README.md describing the exercise.

• Exercise 1
