For Python Frederick's July presentation, I presented on Git and GitHub for beginners who have never used either of those tools before.
In the presentation, I explained the core concepts of Git and demonstrated how to use Git with Visual Studio Code (VS Code). We covered why you would use Git and how you would use it to work with other people.
The demonstration also used GitHub to create a repository for a code project. We looked at a couple of methods of sharing code between people, including directly committing to a shared repository and working with Pull Requests.
The recording from the talk is available on YouTube. Check it out!
The material for the presentation is also available on GitHub. The presentation is in the Python Frederick talks repository.
