This presentation / interactive demo covers how to get started contributing to open source software projects. Who can contribute, types of contributions, and how to make useful contributions are all covered. Significant time will be spent on the concept of, and how to generate, pull requests on GitHub. This presentation builds upon the previous talk covering version control systems. Having a configured (including authentication) GitHub account will enable following along with the "live" demonstrations, helping to cement the lessons learned through practice: https://docs.github.com/en/github/getting-started-with-github/set-up-git
