+title: Introduction to Version Control with Git and GitHub
+author: Peter Hill
+tags: git vcs version control
+---
+
+This week, we had our annual introduction to version control using Git
+and GitHub. Version control is one of the foundational tools of
+software development, whether you're writing small analysis scripts
+for your own experiments, or large HPC simulations with lots of
+collaborators.
+
+This introduction covers the basics of working alone with git, making
+commits, using branches, and pushing and pulling from GitHub.
+
+The slides can be found [here][slides].
+
+Check out [our links to other resources][resources].
