Tutorial: Take Control of Git: Beyond the Basics - Kim Schlesinger, Contentful & Kyle Coberly, Urban Sky

Wednesday June 25, 2025 11:00am - 12:35pm MDT

Bluebird Ballroom 3A

You can commit, pull, and push—but do you truly understand Git? Does it feel more like a fragile system you tiptoe around than a tool that empowers your workflow? If navigating your repository makes you hesitant, it's time to go beyond the basics and build real confidence.

In this hands-on workshop, you’ll learn to:

1. Navigate with confidence: Jump between commits without fear using Reflog, ensuring you never lose your place
2. Refine your workflow: Embrace the safety of version control with patches, diffs, and resets to commit first and edit later
3. Keep your best work: Shape your commit history with checkout file, cherry-pick, and interactive rebase to express your intent clearly

Version control isn’t just a safety net—it’s a tool that amplifies your impact as an engineer. Equip yourself with the professional’s toolkit and make Git work for you!
