Software Setup

Discussion

Details

For this course, we will use GitHub Codespaces, which provides a cloud-based development environment that runs directly in your web browser.

This approach means that no software installation is required on your personal computer, making it much easier to get started.

Your Codespace environment will be Linux-based, so we will be using standard Linux commands and tools throughout the lessons.

Create a repository

  • Log into GitHub and create a new repository for this lesson called greet_me and add a Licence File when creating the repository.

  • From the repository page, open the Code dropdown menu, select the Codespaces tab, and click Create codespace on main.

  • Once your Codespace has been created, open the terminal inside it and run the following commands.

Run the following

BASH 

curl -fsSL https://pixi.sh/install.sh | sh
