The best way to use the GitHub repository is to create a GitHub account, then download the GitHub Desktop application. Once both those steps are done, click the "Clone or download" button on the right side of the repo page (linked to above) and select "Open in Desktop". Now you just need to choose where, on your local computer, you'd like to save all of our class demos. At school, I'd recommend your M:/, and you can also do this at home to have easy access to all the demos at home as well. To update your folder to include the most recent demos, open GitHub Desktop, select the cs20-demos repository, and click on the "Fetch Origin" button. From then on, whenever you want to get the latest demos on your machine, just open the GitHub application, and click on the "Fetch Origin" button.
