This workshop will cover the essentials of Git, GitHub, and GitHub Actions. The content is tailored to domain scientists wanting to work collaboratively on code and add automation to certain parts of their workflows. Topics covered include version control basics with Git, hosting a repository on GitHub, working collaboratively with others, and using GitHub Actions for automation and continuous integration / continuous deployment. Hands-on participation is encouraged. Attendees will benefit the most if they are prepared with a laptop and access to the Git CLI, a GitHub account, and a Docker Hub account.
